  zero-shot-classification + SST-2 sentiment running in worker thread; signals {type:'ready'}
  when models warm; env.useBrowserCache=true for browser Cache API model caching

  new Worker(url, {type:'module'}); wraps calls as Promises; warmup()/onReady()/isReady();
  graceful fallback if Workers unavailable

  header (not query param); local triage badge "0 sats"; imports from edge-worker-client
- js/websocket.js: sentiment() on inbound Timmy chat messages → setMood() (10 s auto-clear)
