// - warmcool: an ordered low→high spectrum (warm reds at the bass end →
|

// stage-bright look.
|
||||
// - colorblind: the Okabe–Ito accessible qualitative palette (vermillion,
|
||||
// orange, yellow, bluish-green, sky-blue, blue, reddish-purple), the most
|
||||
// distinguishable option for deuteranopia/protanopia.

// above, contributed by a deuteranopic player who still found that set hard
|
||||
// to separate. Retunes the six main strings (red / yellow-green / blue /
|
||||
// orange / teal / deep-purple) and keeps its 7/8-string colors unchanged.
|
||||
// - neon: electric, max-saturation hues whose LIGHTNESS deliberately zig-zags
|
||||
// between neighbours (bright→bright→brightest→dark blue→bright green→dark
|
||||
// violet) so adjacent strings separate harder than vivid — a stage/stream
|
||||
// "pop" set, not a vivid duplicate.
|

|
||||
// blue → vermilion → azure → orange → yellow → cream). Unlike the unordered
|
||||
// Okabe–Ito 'colorblind' set, the value ramp teaches pitch low→high AND
|
||||
// survives grayscale/colorblindness; no red/green pair carries meaning.
|
||||
// - ember: a warm, lower-intensity family for long sessions, luminance-stepped
|
||||
// from rust/ember at the bass through warm gold to cream at the treble. The
|
||||
// bass embers stay light enough to clear the near-black scene.
|
||||
// - tapedeck: a vintage-print, slightly desaturated ochre-tinted family
|
||||
// (rust-red → mustard → avocado → teal → faded denim → dusty plum). Muted
|
||||
// hues collapse, so neighbour LIGHTNESS deliberately zig-zags to keep the
|
||||
// dusty mid-strings (avocado/teal/denim) distinct on the dark board.
|
||||
// - crtgreen / crtamber: monochrome CRT-phosphor families (green / amber)
|
||||
// stepped by STRICT ASCENDING LIGHTNESS low→high. Mono sets collapse on hue,
|
||||
// so lightness alone carries the ordering. Verified to stay legible even on
|
||||
// the matching phosphor scene board (green-on-green / amber-on-amber).
|
||||
// - pitchramp: a smooth low→high hue sweep (violet → blue → teal → green →
|
||||
// yellow → warm-white) with rising lightness — memorable + teaches order.
|
||||
// - sunrise: a soft dawn gradient (plum → rose → coral → amber → gold → cream),

// warm and lower-intensity, lightness-stepped low→high.

|
||||
// dependency closure from count-in, from loops, from section-practice, or from the
|
||||
// JUCE seek shim all return the SAME 178-function set, and setLoop() and
|
||||
// practiceSection() call each other directly. So a module carved out of that
|
||||
// component will always need to call back into app.js — and it cannot `import`
|
||||
// app.js to do it, because app.js imports the module, and that closes a cycle the
|
||||
// import-x/no-cycle gate (rightly) rejects.
|
||||
//
|
||||
// So app.js hands its functions DOWN, once, at boot: `configureHost({ playSong, … })`.
|
||||
//
|
||||
// ─── THE FAILURE MODE THIS IS BUILT TO PREVENT ───────────────────────────────
|
||||
//
|
||||
// The obvious way to write this is a plain object with no-op defaults. That is a
|
||||
// TRAP, and we walked into it once already: the plugin loader's host seam defaulted
|
||||
// `populateVizPicker` to `() => {}`, which means that if the wiring call in app.js
|
||||
// is ever dropped, renamed, or drifts, the loader keeps running, the viz picker
|
||||
// silently stops refreshing, and NOTHING — no test, no boot check, no bot — says a
|
||||
// word. A feature just quietly stops existing.
|
||||
//
|
||||
// Two layers stop that here, and the second is the one that actually closes it:
|
||||
//
|
||||
// 1. RUNTIME — reading an unwired hook THROWS. There are no defaults and no
|
||||
// stubs. `host.playSong` either is the real function or it is a loud error.
|
||||
// An unwired hook cannot degrade into a no-op, because there is nothing for
|
||||
// it to degrade INTO.
|
||||
//
|
||||
// 2. STATIC — tests/js/host_contract.test.js asserts that the set of hooks the
|
||||
// modules USE is exactly the set app.js WIRES. This is the important one:
|
||||
// layer 1 only fires if the broken path actually executes, and the whole
|
||||
// danger of this seam is paths that don't run in a smoke test. The static
|
||||
// check catches a drifted or misspelled hook in CI, on a path nobody ran.
|
||||
//
|
||||
// Consequence for anyone adding a hook: add it to the configureHost({…}) call in
|
||||
// app.js *and* use it as `host.<name>`. The contract test fails on either alone —
