- **Voice trigger (big ears):** Voice wake detector calls `AppState.triggerVoiceEars(ttl: nil)` when the wake word is heard, keeping `earBoostActive=true` while the utterance is captured. Ears scale up (1.9x), get circular ear holes for readability, then drop via `stopVoiceEars()` after 1s of silence. 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.
- Voice wake: runtime/tester call `AppState.triggerVoiceEars(ttl: nil)` on trigger and `stopVoiceEars()` after 1s of silence to match the capture window.
- 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.
