- **Voice trigger (big ears):** Voice wake detector calls `AppState.triggerVoiceEars()` → `earBoostActive=true` for ~5s. Ears scale up (1.9x), get circular ear holes for readability, then auto-reset. Only fired from the in-app voice pipeline.
- **Working (agent running):** `AppState.isWorking=true` drives a “tail/leg scurry” micro-motion: faster leg wiggle and slight offset while work is in-flight. Currently toggled around WebChat agent runs; add the same toggle around other long tasks when you wire them.
Wiring points
- Voice wake: see `VoiceWakeTester.handleResult` in `AppMain.swift`—on detection it calls `triggerVoiceEars()`.
- Agent activity: set `AppStateStore.shared.setWorking(true/false)` around work spans (already done in WebChat agent call). Keep spans short and reset in `defer` blocks to avoid stuck animations.
