topkoa de2a42bd35 fix(panes): coerce plugin-supplied pane sizes to numbers
`spec.width` / `spec.height` are plugin-controlled, and the window host builds
window.open()'s feature string by concatenation:

    'popup,width=' + spec.width + ',height=' + spec.height

`spec.width || 380` passed anything truthy straight through. So a width of
'300,menubar=1' would not merely be an invalid size — it would inject window
features. Less dramatically, any non-numeric value produced a malformed feature
string and a pane that failed to open for no visible reason.

They now go through _size(): Number, round, reject anything not finite and
positive, clamp to 120..4000. A hostile or careless value falls back to the
default instead of reaching window.open() at all.

Verified against the obvious inputs: '300,menubar=1' -> 380 (default), '300' ->
300, 0/-50/NaN/{}/'abc' -> 380, 1e9 -> 4000, 5 -> 120.

topkoa 671aba950c chore(panes): drop the leftover adoption diagnostics
A ~15-line console.info dumping computed styles, sizes, child counts and the
element's inline style on every single pop-out. It was instrumentation written
to chase the "panel comes home dead" bug, and it should have gone out with the
rest of the debugging — it survived the cleanup.

Removed rather than downgraded to console.debug: nothing here is worth keeping
even behind a flag. The failures it was built to diagnose are all handled and
commented now, and the paths that can still go wrong (window never loads, adopt
throws) already log a console.error that says what happened.

topkoa 95d6d8a46e fix(panes): keep panes.css last in the pane window's cascade
_copyStyles appended the app's stylesheets to the pane document — which
already links panes.css — so they landed AFTER it. In the app document
panes.css loads last, after tailwind/style/v3, and its rules win ties. In the
pane window that order was silently inverted, letting core styles override the
pane chrome and the .fb-paned placement rules.

Cascade order is not a detail here. "Looks identical" has to include the order
things are said in, or the same markup with the same sheets can still render
differently.

The clones now go in BEFORE pane.html's own link, preserving their relative
order among themselves and leaving panes.css last, exactly as in the app.

topkoa f43779c99e fix(panes): detach the element when the pop-out starts, not when it lands
The window host's place() is asynchronous — it opens the window, waits for
/pane to load, and only then adopts the element in. But the manager emits
`panes:opened` as soon as place() returns, and the chip reacts by putting its
"popped out" stub where the element used to be.

So for that gap the user saw BOTH: the real panel still sitting in its
original spot, and a stub next to it claiming the panel had left. On a window
that never loads, that lasts the full 10s readiness timeout.

Detach the element as soon as we commit to moving it. That is not destructive:
the node keeps its owner document, its listeners and its closures — it is
simply out of the tree, waiting for a document to be adopted into. And if the
window never loads, closePane() puts it straight back at its home, which is
exactly what the failure path already does.

The dock host has no such gap; its place() moves the element synchronously.

topkoa 82aa8a757e fix(panes): harden the persisted host map against unsafe pane ids
A pane id is plugin-controlled, and it becomes a KEY in the persisted
{ paneId: hostId } map. `__proto__` and friends are not ids, they are booby
traps:

  - `map['__proto__'] = 'window'` on a plain object corrupts the map, and
    can reach Object.prototype.
  - `map[id]` on a polluted (or hand-edited) object can return a value straight
    off the prototype chain for a pane that was never remembered at all — so a
    pane could be "restored" to a host nobody ever put it in.

Three layers, because each is a one-liner:

  - Reject `__proto__` / `constructor` / `prototype` as pane ids at
    registration, so they never reach storage.
  - Re-key whatever comes out of localStorage onto a null-prototype object, so
    a corrupt or hand-edited value cannot smuggle a prototype in.
  - Read with an own-property check.

Also from the same review:

  - Removed `window.__fbPaneWindows`. It was exposed for pane-desktop.js back
    when that file needed to reach the window handles; the rewrite dropped that
    need and nothing has referenced it since. Dead global, and its comment
    described a collaborator that no longer exists.
  - Corrected the /pane cache comment. It claimed a stale page would leave the
    window blank, which stopped being true when the readiness check gained a
    `doc.body` fallback — it would still work, just without the pane window's
    own layout. A comment that describes a failure mode the code no longer has
    is worse than no comment.

topkoa cb425ed48d fix(panes): don't hide a docked pane; don't force display; restore visibility
Six more findings from CodeRabbit on #928. Three are real bugs.

1. THE CHIP HID DOCKED PANES. `_onOpened` decided "did the pane take my
   element?" from `ownerDocument !== document`. That is true for a pane in a
   pop-out window — and false for a pane moved into the DOCK, which lives in
   this very document. So docking a pane stamped `.fb-pane-detached`
   (display:none !important) onto the panel the user was looking at, and put
   the stub next to it instead of at its home.

   The element cannot answer this question — `isConnected` is true in a pane
   window, `ownerDocument` is this one in the dock. Both were live bugs. Ask
   the manager, which knows exactly what it handed to the host:
   `panes.elementOf(id)`. That holds for every host, and for reconciling after
   the fact (detail == null), which is what a plugin rebuilding its panel
   mid-pop-out triggers.

2. `.fb-paned` FORCED `display: block !important`. A panel that is
   `display:flex` or `grid` would be silently re-laid-out while detached —
   the exact opposite of "placement only", and precisely the kind of surprise
   this feature exists to avoid. Removed.

   Making a hidden panel visible is a separate job, and it now belongs to the
   manager, which does it without touching the panel's display MODE: clear
   `hidden`, and clear an inline `display:none` if that is how the panel hides.

3. VISIBILITY IS NOW RESTORED. The hosts used to set `el.hidden = false` and
   never put it back, so the docs' "core only changes placement" was a lie and
   a panel's hidden state was quietly lost. The manager stashes both `hidden`
   and the inline `display` on open and restores them on dock: a panel that was
   closed when you opened its pane from the tray goes back to being closed; one
   that was open stays open.

Plus:

- The launcher rebuilt its whole list on every panes:opened/closed — including
  the one fired by clicking a button in that list — destroying the button under
  the user's finger and dropping focus to <body>. It now restores focus to the
  toggled pane's button.
- `_copyStyles` cloned every stylesheet link, including the panes.css that
  pane.html already loads. Skip sheets the pane document already has.
- Docs: the chip may route to the DOCK, not always a window (it goes through
  detach() → the host router). `header` precedence was documented backwards —
  an explicit `header` wins. And the visibility contract above is now written
  down rather than being a surprise.

topkoa b74a364857 docs(panes): re-attach the chip when the panel is rebuilt
A plugin that rebuilds its panel (Camera Director does, on every mode
change) takes the chip with it. attachChip() returns a detach(); call it
before re-attaching, and again in teardown, or you leave a stub pointing at
DOM that no longer exists.

topkoa 859b0036e5 fix(panes): review fixes — stranded elements, duplicate listener, class clobber
Three real findings from CodeRabbit on #928, all in current code.

1. closePane() adopted the element out of the pane window ONLY when its
   original home was still connected. If the panel never had a parent (a
   plugin that builds it lazily and hands it straight over) or its container
   was torn down while the pane was out (a screen change), the whole block was
   skipped — leaving the element inside a window we then close, which strips
   every listener in its subtree. That is exactly the "comes home dead" failure
   this ordering exists to prevent; the guard just moved it from the common
   path to the rare one, where it is far harder to spot.

   Adopting and re-homing are two different jobs and only one of them is
   allowed to fail. Adopt UNCONDITIONALLY — that is what rescues the element —
   and insert only when there is somewhere to insert it. With no home the
   element ends up owned by this document but not in it: detached, intact,
   listeners alive, ready for the plugin to re-insert.

2. The pane window's `beforeunload` handler was registered TWICE, comment block
   and all — a bad scripted edit on my part. Harmless (the handler is
   idempotent via panes.isOpen) but dead duplicate code. Also fixed the stale
   comment further down that still claimed there was no beforeunload listener
   at all.

3. _copyStyles ASSIGNED className on the pane document's <html> and <body>
   instead of merging. pane.html sets `class="fb-pane-window"` on <html>, and
   panes.css hangs the pane window's own chrome off exactly that — so copying
   the app's classes over it silently took the pane window's own layout with
   them. Merge both class lists, and append the interface-scale inline style
   rather than replacing the attribute.

Also guarded the docs' integration example behind a feedBack.panes check: the
doc says the API is optional, and then showed an example that would throw on a
host without it.

Not applicable (reviewed against e5cbea2, the branch's first commit, before the
rebuild): the prototype-pollution findings in pane-bridge.js and pane-mirror.js,
and the `panes[]` manifest validation in plugins/__init__.py. All three files are
gone — 188bdaa deleted the entire cross-realm bridge, mirrorGlobal, and manifest
layer when panes switched to moving the real DOM node.

topkoa 1e5282e27e fix(panes): get the element out before the pane window's document dies
Docking a popped-out panel brought it home DEAD. It rendered perfectly —
right markup, right size, right place — and every control in it was inert:
the close button, the sliders, the presets, even the pop-out chip. A
photograph of a panel.

Closing a pane window tears down its document, and the panel was still
inside it. The node itself survives (the manager holds a reference), but
every event listener in its subtree goes with the document that hosted
them. Two paths did this:

  1. closePane() called the host's unplace() — which closes the window —
     BEFORE adopting the element back. Order is now reversed, and the
     comment says why so nobody helpfully "tidies" it back.

  2. The user closing the pane window themselves was only noticed by the
     `closed` poll, which by definition runs AFTER the document is gone.
     The window now gets a `beforeunload` listener that brings the element
     home while its document is still alive.

That listener has to be attached AFTER /pane loads: window.open() hands
back a throwaway about:blank document, and anything registered on it is
discarded when the real page replaces it. This is the same trap that made
the pane window blank in the first place — adopt into about:blank and the
panel is destroyed a moment later — and it is now handled in both places.

The `closed` poll stays, but only as a last-resort net for a CRASHED pane
window, where nothing can be saved.

Also fixed while chasing this:

  - The chip stamped `.fb-pane-detached` (display:none !important) onto the
    element to hide it in the main window — and that element is the one we
    move, so the class travelled with it and blanked the pane window. The
    chip now only hides an element the pane did NOT take, and marks the hole
    with its stub otherwise. "Did not take" is an ownerDocument test, not
    isConnected: a panel sitting in a pane window IS connected, just not
    here, and a plugin that rebuilds its panel (Camera Director does, on
    every mode change) re-runs attachChip while popped out.

  - The stub was inserted "before the element", which is nowhere — the
    element has left the document. The manager now hands over the element's
    recorded home, and the stub goes there.

  - GET /pane sent no cache headers. A stale copy is especially nasty here:
    the opener waits for an element inside that page before adopting, so an
    old cached version means the pane window just sits there blank.

Verified in the desktop app: pop out, use the controls in the pane window,
dock back, use them again. Panel comes home alive.

topkoa 9e9f0fdac6 fix(panes): adopt into the real pane document, not about:blank
Both pop-outs opened blank.

window.open() returns immediately, and the window it hands back already has
a document — an `about:blank` one, whose readyState is 'complete'. So the
host cheerfully adopted the panel into THAT, it worked for a few
milliseconds, and then /pane finished loading, replaced the document, and
took the panel with it. Blank window, vanished element.

Waiting for 'load' is no better: it may already have fired for about:blank
before we could listen.

So don't trust readyState and don't trust 'load' — wait for the one thing
that exists only in the document we actually want: pane.html's
#fb-pane-root. Poll for it (guarding the cross-document window while it is
mid-swap), give up after 10s, and on failure bring the element home rather
than stranding it in a window that never loaded.

Also drop the popup's 'beforeunload' listener: it was registered on the
about:blank window and discarded along with it, so it never fired. The
`closed` poll is what notices a user shutting a pane window — as it must be
anyway, since a crashed renderer never says goodbye either.

topkoa 188bdaa837 feat(panes)!: move the real element, instead of rebuilding it
The first cut of this got the model wrong. A pane was a SECOND
implementation of the plugin's panel — its own sliders, its own styling,
driven over a cross-realm bridge (ctx, a state store, capability RPC,
mirrorGlobal, a stream sampler). Popping out gave you something that
resembled the panel you popped, and every feature it did not reimplement
(presets, tabs, EQ, language) was simply gone.

What a user wants from "pop this out" is the thing they popped out.

So: MOVE THE REAL ELEMENT. Same-origin windows can adopt each other's
nodes, and an adopted node keeps its event listeners and its closures.
The panel goes on running the plugin's own code, against the plugin's own
state, in the plugin's own realm — it is merely being DISPLAYED in another
window. Copy the app's stylesheets into that window and it looks identical
too, because it is identical.

The plugin's side collapses to two lines:

    feedBack.panes.register({ id, title, element: () => panelEl });
    feedBack.panes.attachChip(panelEl, id);

and everything comes along: the CSS, the listeners, the presets, the
state. Nothing to keep in step, because there is no second copy.

Deleted, all of it now pointless: pane-bridge (ctx + transports), pane-hub
(the cross-realm server), pane-runtime (the pane realm's boot), pane-streams
(the rAF sampler that existed because an AnalyserNode can't cross a window),
pane-mirror (mirrorGlobal), pane-plugins + the manifest `panes[]` key and its
server-side validation, panes.state(), and both built-in demo panes. ~1200
lines. None of it was wrong — it was all correct machinery for the wrong
problem.

Consequences worth knowing:

- The window MUST be opened by the renderer with window.open(), not by the
  desktop's main process: a window we did not open gives this realm no handle
  to its document, and without the handle there is nothing to adopt into.
  Electron turns the same-origin window.open() into a real BrowserWindow
  anyway (setWindowOpenHandler → 'allow'), so we get the OS window AND the
  live DOM link. The desktop side finds it by frame name.
- `.fb-paned` neutralises PLACEMENT only (position/inset/width/z-index/shadow).
  A plugin panel is nearly always a fixed overlay pinned to a corner of the
  app; alone in a 380px window that positioning is nonsense. Colours, borders,
  padding, fonts and the panel's own internal layout are untouched — the whole
  promise is that what you popped out is what you get.
- The element is returned to its EXACT home on dock: same parent, same position
  among its siblings.
- The plugin's code still runs in the main window. So a document.body
  .appendChild() inside a panel (a tooltip, a popover) lands in the main
  window, not the pane — anchor to the panel instead. And a continuously
  animating panel may run slowly while the main window is backgrounded, since
  its rAF lives there. Both documented.

topkoa 330995588c feat(panes): panes.state(id) — let a plugin apply its own pane's values
mirrorGlobal covers the case where a pane drives a plain global that some
renderer reads each frame. It does not cover the far more common one: a
plugin whose MAIN-realm code is the authority — it clamps, it persists, it
emits events, it owns the audio graph or the camera rig — and which must
therefore APPLY the pane's values itself rather than have core splat them
somewhere.

Camera Director is the case that forced this. Its brain is the sole writer
of the camera store, the sole broadcaster on splitscreen's channel, and the
only thing that clamps an axis to its legal range. A pane cannot write
window.__h3dCamCtl behind its back without desynchronising its presets, its
persistence, and the panel's own sliders — and running the brain inside the
pane realm would make it a SECOND store writer and a second broadcaster,
racing the real one.

So: `panes.state(id)` hands the main realm the open pane's store
(get/set/all/subscribe). A plugin seeds it on `panes:opened`, subscribes,
and applies what comes back through its own API. The pane stays
realm-agnostic — it only ever touches ctx.state — and the plugin stays the
single source of truth.

For that to work, the hub now broadcasts EVERY change to the store, not just
the ones a pane asked for: it subscribes to the store on connect rather than
echoing pane-originated writes by hand. A value the plugin clamps or corrects
therefore reaches the pane window immediately, and there is exactly one path
by which state arrives in a pane — so it cannot drift.

topkoa 254e26bb3a feat(panes): mirrorGlobal, manifest-declared panes, and the plugin docs
Three things a plugin needs before it can actually use panes.

## mirrorGlobal — the camera-director problem

The 3D highways read their free camera from a plain global,
`window.__h3dCamCtl` (highway_3d/FREECAM_BRIDGE.md), once per frame in
_resolveFreeCam(). A camera panel in the main window just writes that
object and the camera moves. A panel in a POP-OUT window cannot:
window.__h3dCamCtl there is a different object in a different realm, and
writing it moves nothing.

So a pane declares one field — `mirrorGlobal: '__h3dCamCtl'` — and
pane-mirror.js (main realm, where the renderers live) copies that pane's
state onto the global whenever it changes. highway_3d, keys_highway_3d
and drum_highway_3d are NOT modified and do not know panes exist.

The rule that makes it work: MUTATE THE OBJECT, NEVER REPLACE IT. A
renderer may be holding the reference, and swapping in a new object would
leave it reading an orphan. Keys the pane doesn't set are left alone
rather than deleted — the global may carry a renderer's own bookkeeping.
Closing the pane deliberately leaves the global as-is: closing the camera
panel should not snap the camera back to a default, which is exactly what
happens today (nobody clears __h3dCamCtl).

## Manifest-declared panes

    "panes": [{ "id": "camera_director", "title": "Camera Director",
                "script": "panes/camera.js", "mirrorGlobal": "__h3dCamCtl" }]

Declaring a pane beats calling panes.register() from screen.js because it
becomes openable FROM THE RAIL OR THE TRAY WITHOUT THE PLUGIN'S SCREEN
EVER HAVING BEEN VISITED — core registers a stub from the manifest and
fetches the script only when the user opens it. A pane you can only reach
by first navigating to the screen it was meant to replace is not much of a
pane.

The script sets `window.feedBackPane_<id> = { mount, unmount }`, mirroring
the existing window.feedBackViz_<id> convention, and the SAME file is what
a pop-out window loads in its own realm.

`script` is validated as a relpath under the plugin's src/ and served
through the sandboxed /api/plugins/<id>/src/ route — the containment rule
`styles` already has for assets/. Traversal, absolute paths, drive letters,
backslashes and non-.js are rejected; a bad entry is dropped with a warning
rather than failing the whole plugin, because one malformed pane should not
cost the user a working plugin.

Note the projection is written TWICE — _nav_entry() and the /api/plugins
route re-project independently — so panes had to be added to both, plus the
pending branch (a pane can be opened while its plugin is still installing
deps; the script is fetched on open, not at discovery).

## docs/plugin-panes.md

The contract, and the one rule it all hangs on: mount(root, ctx) runs in a
realm that may not have the app in it. Everything comes through ctx, or the
pane works docked and silently dies popped out.

Verified: manifest validation rejects ../.., C:\, non-.js, dupes and
missing fields while passing a good entry; /api/plugins projects panes[] for
all 20 plugins. mirrorGlobal mutates the global IN PLACE — a reference held
the way _resolveFreeCam holds it sees the change, and a renderer's own field
on that object survives — both for a local write and for a write arriving
over the channel from a pop-out realm.

pytest: 2401 passed, 8 failed — all 8 reproduce on a clean main (including
the one in tests/test_plugins.py) and are unrelated.

topkoa d508380532 feat(panes): desktop host — real windows and the system tray
Registers a `desktop` pane host at priority 20, above the browser pop-up
host (10) and the dock (0), whenever the Electron bridge exposes
feedBackDesktop.panes. A popped-out pane then gets a real BrowserWindow:
it remembers where you put it, can float above everything, minimizes to
the system tray, and appears in the tray's menu.

In a plain browser — or on an older desktop build that predates the
bridge — this file registers nothing and the browser pop-up host handles
detach exactly as before. Nothing else in the pane system changes. That
is what the host registry is for.

Two things only this realm can decide, so it owns them:

- The user closed a pane window (or it crashed). Close the pane, or the
  dialog its pop-out chip hid never comes back and the user is left with
  no way to reach their own UI.
- The tray asked to toggle a pane it has no window for. Main cannot know
  what opening one means — the pane might belong in the dock — so it asks.

Unlike a browser pop-up, this host needs no user gesture, so it sets
autoRestore: true — a pane you left popped out comes back popped out,
where you left it, on the next launch.

Pairs with got-feedback/feedBack-desktop#103.

topkoa fefb9051a4 feat(panes): pop-out windows — the pane realm, hub, and remote transport
A pane can now leave the main window entirely. Same `mount(root, ctx)`,
same file, different JS realm — which is what the ctx-only contract in the
previous commit was for.

## A purpose-built document, not the app shell with a flag on it

`GET /pane` serves static/panes/pane.html: the bridge, the runtime, and
the pane's own script. No highway, no library, no v3 shell, no <audio>,
no Tailwind.

The splitscreen follower takes the other road — it reloads the whole app
at `/?ssFollower=1` and hides what it doesn't want — and pays for it with
an anti-flash block that must run before any script parses (index.html),
bail-outs in app.js and shell.js, and ~40 lines of CSS hiding core
elements by id. It loads the entire app to throw it away. A pane window
has nothing to throw away, so it boots in milliseconds and there is
nothing to flash.

The cost is that `window.feedBack` in a pane realm is a deliberate,
documented SUBSET. The runtime installs exactly what a pane is promised —
`panes.register`, and the no-op chip/dock calls a shared script may make
at load — so a pane reaching for something it was never given fails
loudly at authoring time instead of subtly at runtime.

## The channel

BroadcastChannel('feedback-panes'), same origin. This works only because
Electron's setWindowOpenHandler returns `action: 'allow'` for same-origin
URLs: `deny` would push the window to the system browser, a different
Chromium instance, where BroadcastChannel cannot reach it and the pane
would silently never sync. That flag is load-bearing.

  hello -> snapshot   resync-on-open, always. The snapshot is the only way
                      the pane realm learns anything.
  state               main is authoritative. A pane's write is a REQUEST;
                      main applies it and echoes to every realm, so a
                      losing write self-corrects instead of splitting brain.
  rpc / rpc:reply     ctx.call() -> the capability bus, with a 10s deadline.
                      Without one, a main window that died mid-call leaves
                      the pane's promise pending forever.
  event               allowlisted bus events, JSON-safe. A CustomEvent
                      carrying a DOM node (highway:canvas-replaced does)
                      would throw on postMessage and take the channel down
                      for everyone, so detail is round-tripped through JSON.
  stream              one coalesced message per pane per frame, OVERWRITING
                      anything not yet flushed. Queueing would build a
                      backlog: Chromium throttles a backgrounded window, and
                      the main window is exactly what's backgrounded while
                      the user looks at the pane.
  sub / unsub         refcounts the main-realm sampler.
  bye                 both directions.

## The follower clock

The pane extrapolates between broadcasts: anchor + observedRate * elapsed,
capped at 2s. observedRate is learned from the broadcasts themselves
(dt/dwall) so it tracks the speed slider without being told about it, and
seeks/pauses are excluded from the fit — a jump is not a tempo. Capping it
means a dead main window decays into a frozen clock rather than one that
confidently runs away. This is splitscreen's hard-won trick, generalized:
panes just call ctx.playhead().

## Failure modes, all of them

- Main window closes -> `bye {main-closed}` and the pane says so plainly,
  rather than showing a frozen playhead that looks live. The host also
  closes its windows outright; a pane that cannot be fed should not be on
  screen.
- Pane window X'd or crashed -> a `closed` poll reaps it (a crashed
  renderer never sends `bye`), the pane closes, and the chip's dialog comes
  back. Without this the user's dialog stays hidden with no way back.
- Popup blocked -> a toast, and we bail BEFORE the manager records
  anything, so the caller's dialog stays exactly where it was.
- Nobody answers `hello` in 5s -> the window says so instead of spinning.
- A pane with no `script` is a closure in this realm and cannot honestly
  cross a window boundary. The window host declines it (canHost) and the
  router falls back to the dock.
- A browser blocks window.open() outside a user gesture, so a popped-out
  pane cannot be auto-restored on page load — it would only ever produce a
  "blocked" toast. Such a pane comes back in the DOCK, and the chip pops it
  out again on the next click. (autoRestore: false. The desktop host will
  set it true.)

Hosts may now declare `remote: true`, meaning the pane's mount() runs in
another realm: the manager then owns only the authoritative state store and
never calls mount() itself. That is the seam the Electron BrowserWindow +
tray host drops into next, with no change here.

Verified: popped Now Playing and Mixer into real windows. The pane realm has
no window.highway, no capability bus and no <audio>, yet the Mixer renders
its faders via ctx.call('audio-mix','list-faders') across the channel — and
dragging that fader IN THE PANE WINDOW moved the main window's song volume
to 55 and persisted it. Closing the pane window un-hid the mixer dialog,
removed the stub and restored the chip, while the other pane window stayed
open.

topkoa e5cbea2e9f feat(panes): core detachable pane system + pop-out chip
The option-heavy player UIs (mixer, camera director, viz, audio routing)
all live in the rail popovers, which are exclusive: openPopFor() closes
the last one before opening the next. You cannot watch the mixer while
riding the camera, and both vanish the moment you look at the highway.

Add `window.feedBack.panes` — a core registry for live UI that is
authored once as `mount(root, ctx)` and hosted anywhere. Panes are
non-exclusive, and they survive song switches structurally: the dock is a
body child outside every .screen, so the per-song teardown never sees it.

The adoption cost for a plugin is two calls:

    feedBack.panes.register({ id, title, icon, mount, unmount });
    feedBack.panes.attachChip(myExistingDialogEl, id);

attachChip injects THE standard pop-out chip. Clicking it opens the pane
and hides the plugin's dialog, leaving a stub to bring it back. Core owns
the hide/restore, so every plugin's pop-out looks and behaves the same —
which is the point. It hides via a dedicated .fb-pane-detached class, not
.hidden/[hidden], because the dialogs we attach to already toggle those.

Everything a pane may touch arrives through `ctx` — never a global. That
is what will let the same mount() run inside a pop-out window, a separate
JS realm with no window.feedBack, no window.highway and no audio graph:

  ctx.call(domain, cmd, payload)  -> the capability bus
  ctx.on(event, fn)              -> the feedBack bus (allowlisted)
  ctx.subscribe(stream, fn)      -> playhead / meters
  ctx.state.get/set              -> persisted, main realm is the only writer
  ctx.playhead(), ctx.song(), ctx.toast(), ctx.close()

ctx tracks every subscription it hands out and drops them on unmount, so
a pane cannot leak listeners across a dock/undock cycle.

Streams exist because an AnalyserNode cannot cross a window boundary:
levels are reduced to numbers in the realm that owns the audio graph.
One shared rAF loop, refcounted against live subscriptions, dirty-checked
before fan-out, and stopped dead when the last pane closes.

Hosts register themselves with the manager rather than being imported by
it — the dock lands at priority 0 (the floor, always available), so the
OS pane window can drop in later without this code changing.

Ships two built-in panes: Now Playing (the reference pane — reads the bus,
a stream, and levels, and touches no globals) and Mixer (the same faders
as the rail, via ctx.call('audio-mix', ...), with the chip attached to the
real #mixer-control). Plus a "Panes" rail popover to open panes that have
no dialog of their own; the system tray will mirror that list.

Note the dock sits at z-index 110, not on the docs/plugin-v3-ui.md ladder
(transport 20, rail 30, popovers 40) — those live INSIDE #player's
stacking context, and #player is itself fixed at z-index 100. A dock below
100 is invisible on the one screen panes exist for. Body-level ladder:
#player 100 < dock 110 < toasts 120 < modals 200.

Pop-out windows, the system tray, manifest-declared panes and mirrorGlobal
(the window.__h3dCamCtl proxy the camera director needs) follow.

Kris AndersonandClaude Opus 4.8 14d116d827 fix(highways): validate panel index before indexing the camera map
_resolveFreeCam() (keys/drum) and _freeCamFor() (highway_3d) guarded the panel
map lookup with only `i != null`, so a non-integer / negative / string index
from panelIndexFor() could resolve an unintended or inherited property (e.g.
map['toString']) instead of cleanly falling back to the global camera. Gate the
index on `Number.isInteger(i) && i >= 0` before `map[i]`, matching the hardening
already applied in _bgPanelKey(). Extend the resolver tests with float/string
(prototype-key) cases. Behavior change only for malformed indices.

Kris AndersonandClaude Opus 4.8 0d4d8229c7 fix(highways): address review — bg-key alias, drum cam guard, resolver tests
Three review findings on the per-panel camera work:

- highway_3d: _bgPanelKey() resolved splitscreen via window.feedBackSplitscreen
  only, while _freeCamFor() uses the feedBackSplitscreen||slopsmithSplitscreen
  alias it claims to "mirror". If the rename lands, per-panel background settings
  would silently stop being per-panel while the camera stayed per-panel. Resolve
  the alias the same way in _bgPanelKey.
- drum_highway_3d: applyCamera()'s "before first positionCamera()" guard tested
  `_camBaseH == null`, but _camBaseH/_camBaseD were initialized to 0, so the guard
  never fired (and could apply a base-0 pose for a frame). Initialize to null.
- keys + drum: the PR claimed the Camera Director resolver was unit-checked, but
  nothing exercised it. Extract the resolver into pure, exported helpers
  (_resolveFreeCam + _ssApi), delegate the per-instance _freeCamFor to them, and
  add tests/camera_bridge.test.js covering per-panel select, global fallback,
  null-when-absent, throw-safety, and the slopsmith-alias resolution. Drum 15→21,
  keys 50→56, all pass; behavior unchanged.

Kris AndersonandClaude Fable 5 5aa336961c feat(highways): per-splitscreen-panel Camera Director cameras
Make the three 3D highways read the Camera Director bridge per panel so each
splitscreen panel renders its own camera (independent orbit/height/zoom/tilt/pan),
instead of all panels sharing the focused camera.

- Add a shared `_freeCamFor(canvas)` resolver to each highway: prefer this panel's
  entry in `window.__h3dCamCtlPanels[panelIndexFor(canvas)]`, fall back to the
  global `window.__h3dCamCtl`, else null (100% stock). Defensive on the splitscreen
  global name (feedBackSplitscreen || slopsmithSplitscreen), NaN-safe, allocation-free.
- highway_3d (guitar): source `_freeCam` from the resolver (was global-only).
- keys_highway_3d: adopt the bridge for the first time — layer dolly/height/orbit +
  pan/pitch offsets onto the pan/zoom follow rig at the camera write.
- drum_highway_3d: adopt the bridge — new per-frame `applyCamera()` folds the static
  base pose + kick-pulse dip + free-cam offsets.
- In a follower (popped-out) window there is one panel, so the resolver yields
  whatever camera the plugin set in that window; no highway change needed for pop-out.

Camera Director absent → resolver returns null → renderers behave exactly as before.
Bump each plugin patch version. Existing plugin tests pass (drum 15, keys 30); the
keys "default look unchanged" test confirms the stock path is byte-identical.

Three fixes from PR review of the per-pane tuner:

- Sync no longer writes back. _syncAspectPanel dispatches synthetic input
  events to refresh slider labels; guard those with _aspectSyncing so the
  slider handler skips the write. Previously opening/switching a target
  populated a full override for every field (defeating sparse inherit) and
  spammed localStorage.

- Unchecking "Override held hFOV" on a pane target now clears the override
  key (via _aspectClearVal) so the pane re-inherits the base value, instead
  of pinning hfovDeg:null in the override. On the base target it still sets
  the explicit auto (null).

- _aspectPrunePanes now prunes the matching __h3dAspectReadout slot and drops
  a dangling __last, so the readout cache can't grow unbounded as songs and
  arrangements churn.

topkoaandClaude Opus 4.8 5ef163e9f9 Key wide-pane overrides by arrangement, not the split panel index
The Target picker disappeared in split because it keyed panes off the
external splitscreen panel index (panelIndexFor), which isn't always
available — both panes then collapsed to a single 'main' key and the
one-pane row-hide kicked in.

Key panes by arrangement name instead ('arr:Bass'): distinct between split
panes AND stable across songs, with no dependency on the split plugin. A
per-instance id ('pane:N') is the fallback when a pane has no arrangement.
Only arr:* overrides persist to localStorage (instance-id fallback keys are
session-only, so they can't leak a new key each reload). This also gives
nicer semantics — a pane's framing follows its arrangement into the next
song.

Key overrides by the durable split slot again ('main' | 'panel<idx>', via

__panels to localStorage. Keep the anti-flicker fixes that were the actual
cause of the earlier dropdown churn (prune stale panes, rebuild only on a
pane-set change, never rebuild while the select is focused). The slot key is
latched to the last real slot so a transient null from panelIndexFor during
a song/layout transition can't flip it to 'main' and drop the override for a
frame; it resets in destroy() for instance reuse in another slot.

The Target dropdown keyed panes off feedBackSplitscreen.panelIndexFor,
which can return the focused index for any canvas — so both split panes'
keys ping-ponged, rebuilding the <select> every frame (flicker) and
listing wrong/duplicate entries. The registry also never dropped panes
from a prior song or a closed split.

- Key each pane by a stable per-renderer-instance id (_paneUid, assigned
  once in init) instead of the split panel index.
- Prune panes not reported within ~1.5s (song change / split teardown).
- Mark the dropdown dirty only when the pane SET changes, not on every
  per-frame re-report, and skip rebuilding while the <select> is focused.
- Hide the Target row entirely when there's a single pane.
- Label panes by arrangement name, falling back to "Pane N".

Per-pane overrides are now session-only (keyed by ephemeral instance ids),
so they're no longer persisted to localStorage.

topkoaandClaude Opus 4.8 9f0d48cb1f 3D highway wide-pane tuner: dismiss + per-pane targeting
Two usability gaps in the wide-pane framing tuner:

- No way to dismiss the panel. Add a × close button to the header and make
  the Shift+A shortcut open/close the panel (reveal/dismiss). The A/B
  enabled toggle now lives as a checkbox in the panel, so closing the panel
  no longer changes the framing state.

- Edits hit every split pane at once. Add a Target selector (All panes, or a
  specific pane labelled by its arrangement, e.g. "Panel 1 — Rhythm"). Per-
  pane edits write a sparse override map (__panels[key]); each renderer
  resolves the shared base with its own pane's overrides laid on top via
  _resolveTuneFor(paneKey), so one pane can be framed independently. Reset on
  a pane clears its override (re-inherits the base); Copy exports the resolved
  values for the selected target. The live readout is keyed per pane.

Panes are discovered from the existing per-panel key (_bgPanelKey /
feedBackSplitscreen.panelIndexFor) and self-register each frame for the
picker. Overrides persist to localStorage alongside the base.

Tests extended in tests/js/highway_3d_wide_fov.test.js.

cross-links (to the spec's renumbered §6/§8/§9.5). The hand-editing guide
