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. Signed-off-by: topkoa <topkoa@gmail.com> |

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.
