Each note in the sequence table has a ▶ button and the whole row
is clickable. Plays a single oscillator with the correct envelope,
filter, and frequency for that note. Highlights the corresponding
hex byte, table row, and byte bar while it plays.
Also added MeshAudio.getContext() accessor for audio lab to create
individual notes without duplicating AudioContext.
Instead of silently dropping notes or hoping gesture listeners fire,
show a clear overlay on first packet if AudioContext is suspended.
One tap resumes context and removes overlay. Standard pattern used
by every browser game/music site.
When audio was previously enabled, registers one-shot click/touch/key
listener to init AudioContext on first interaction. Any tap on the
page is enough — no need to toggle the checkbox.
restore() was creating AudioContext without user gesture (on page load
when volume was saved), causing browser to permanently suspend it.
Now restore() only sets flags; AudioContext created lazily on first
sonifyPacket() call or setEnabled() click. Pending volume applied
when context is finally created.
audio.js is now the core engine (context, routing, voice mgmt).
Voice modules register via MeshAudio.registerVoice(name, module).
Each module exports { name, play(ctx, master, parsed, opts) }.
Voice selector dropdown appears in audio controls.
Voices persist in localStorage. Adding a new voice = new file +
script tag. Previous voices are never lost.
v1 "constellation" extracted as audio-v1-constellation.js.
AudioContext starts suspended until user gesture — now resumes on
setEnabled(). Also added sonifyPacket to animateRealisticPropagation
which is the main code path when Realistic mode is on.
