highway: make the missed-note gem visible + provider-color-driven

[ahonnecke]

Problem

The note-state provider (feedBack#254) lets a scorer flag a note 'miss', but _paintGemGlow rendered every miss as one hardcoded-red circle at globalAlpha = 0.4·alpha, drawn over the gem at r·1.05:

• It ignored the provider's color (which hit/active already honor), so a scorer can't choose a non-colliding hue. The hardcoded red also sits directly on the E string's own color (#ff3c3c in DEFAULT_STRING_BRIGHT), so a missed low-E note is unreadable.
• At 0.4α over a same-size circle — with the provider's short transient alpha — a miss is effectively invisible.

Change

_paintGemGlow's miss branch now:

• Honors ns.color — parsed into the radial-glow stops (fallback purple #c04bff, deliberately away from the red E string).
• Renders a radial glow to r·2.1 + a crisp ring at r·1.2 so a missed note reads at a glance the whole way down the highway.
• Keeps the center tint light (0.32α) so the note colour + fret number (drawn on top by the caller) stay readable.

One file, static/js/highway-state-primitives.js. No API or contract change — a provider that returns a bare 'miss' (no color) simply gets the purple default; one that returns { state:'miss', color } gets its color.

Pairs with a companion note_detect change that makes misses persist across a play (so they light up as the note approaches on the next loop/play), but this render fix stands alone.

📝 Walkthrough

Walkthrough

The missed-note effect now uses the configured provider color, a larger radial glow, and a wider outlined ring. Glow and ring opacity scale with normalized alpha. A purple fallback applies when color parsing fails.

Changes

Missed Note Rendering

Layer / File(s)	Summary
Provider-colored miss effect static/js/highway-state-primitives.js	_paintGemGlow now renders missed notes with a provider-colored radial glow and outlined ring. The effect uses a purple fallback, scales opacity with ns.alpha, and preserves note readability.

Update the stale color description.

The comment still describes the effect as red. The implementation now uses ns.color with a #c04bff fallback.

Proposed comment update

-        // Bold, unmissable red so a missed note reads at a glance the whole way
+        // Bold, provider-colored glow so a missed note reads at a glance the whole way

ring draw to compute one validated, normalized hex color with the purple
fallback, then reuse that value for RGB extraction and hwState.ctx.strokeStyle.
Remove the separate raw ns.color fallback so invalid input produces the same
fallback color for both draws.

Note

GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer.

[ahonnecke]

Addressed in the latest push — the miss glow and ring now derive from a single validated hex (an invalid ns.color falls back to purple for both, instead of only the glow).
