Ghost (src/ghost/):
- format.ts: pure, headless-testable core — int16 (cm position / milli scale)
quantization, base64 localStorage envelope (blobbo:ghost), linear sampling.
- recorder.ts: 15Hz fixed-step recorder, ~5min cap, saves quantized track on a
new best (time <= best, matching game.ts's pre-emit best update).
- player.ts: translucent (~0.35) desaturated ghost + eyes, slight bob, replays
in race time with interpolation; spawns on race:started, despawns on finish.
- install.ts: installGhost(world, blob) wiring both to the frozen race events.
Title (src/ui/title.ts): installTitle(world, {ready}) — CSS bubble-letter
BLOBBO wordmark with paint-drip accents, pitch, controls card, PLAY. Loading
blob-dot while a boot promise is pending. Emits ui:play exactly once inside the
user gesture (audio-unlock friendly), then fades and never returns. Shows saved
best time + "ghost ready".
Demo (demos/lane-h.html + src/demo/lane-h.ts): scripted 20s circle run — title
gates start, run 1 records, later runs replay the ghost on the same path.
Keys: G wipe ghost, R restart, P snapshot.
verify-drift.ts: numeric acceptance (esbuild+node) — max drift 0.0058m vs 0.5m
blob radius. Emits ui:play only; no edits outside owned paths.
