Testable-in-node math extracted ahead of the WebAudio/Phaser layers:
- audio/scheduling.ts: look-ahead beat grid (dueBeats never repeats or skips a
beat however ragged the timer wakes; burst-capped for suspended tabs)
- audio/filterCurve.ts: the location filter's exponential cutoff ramp — the
door-opening sweep, in frequency-space so it blooms late like a real door
- ui/style.ts: chunky pixel widget kit sharing the doll PALETTE
- ui/typo.ts: deterministic drunk-typo/typing/wobble renderer (seeded, no
Math.random)
- ui/juiceEvents.ts: EventMap extensions via declaration merging, so
door:phoneTheatre types correctly without editing frozen data/types.ts.
