Music text must never reach the model — "play Africa by Toto" +is a command, not a conversation. So the ghost got its own rules brain +(`music/brain.ts`): deterministic intent parsing for play/skip/pause/resume/ +stop/louder/quieter, with mood words ("something chill") mapped to fixed, +curated search strings — replayable bit-for-bit, zero tokens, forever. The +LLM brain is now skipped entirely when the rules brain catches music. + +**The wall that mattered:** resolving a song name to a playable track without +scraping. The answer is the official YouTube Data API v3, server-side only +(the key never reaches the browser), embeddable-filtered, with the embed +player riding *visible* inside the ghost's control bubble — no 1px hidden +frames, no re-built player UI. Search costs 100 quota units, durations 1 +more; the free tier covers hundreds of summons a day. No key: the desk says +so calmly and the ghost stays in the floor — the refusal is an honesty +label, not an error. + +**The bugs this round caught before they shipped:** +1. **The arrive state was a trap.** The first draft set `state: "arriving"` + and never advanced it — the beat bob is gated on `"out"`, so the ghost + would have materialized and stood frozen forever.

The ghost was a new character (skirt, wisp, pulse) when the ask was the desk head in red. Rebuilt on the same 32x32 viewBox, r=13 volume, and the SHARED .desk-eye-g/.desk-eye classes — the eye choreography is now glance-for-glance identical to the black head. Skirt, wisp, pulse and wander removed from CSS; the ghost's own motion is arrive/sink + beat bob. 2. 'setVolume is not a function' — the IFrame API player's methods only exist after onReady. Every player call now goes through the ready promise; volume sets on ready. The stage's React-owned wrapper persists through the full/mini deck flip so the player is created once and the music never dies on a collapse; the ready promise resets on unmount. skip now rides the summon's three-track queue instead of doing nothing.
