## 6. Hidden Timers Verification (`perf/hidden-timers.mjs`)
Verifies that non-playback UI intervals (`chips`, `reanchor`, `rotateChips`, `flush`, `checkBuildTag`) suspend while the document is hidden and restore upon visibility, while essential background intervals (`maybeCheck`, 120s resume check) remain active:
```bash
node perf/hidden-timers.mjs
```
Exits with code 0 on success, or code 1 if any interval fails to pause, fails to resume, or if page errors occur.
