- Reset between speakers. Use the stage timer for an agenda that advances through named segments automatically.

Quick reference
| Offline | After one successful visit, this route can reopen from the service-worker cache. Keep the tab or installed app open for sound and live state. |

| Browser limits | Fullscreen needs browser support and a user action. Sound still requires the page or installed app to remain available. |
Questions and answers
Can I control the display from another device?
No. There is no remote controller. A shared setup copies settings, not live playback or pause commands.
Can I rely on a cue while the laptop sleeps?
Keep the device awake and the page open for cues. The countdown catches up when the browser resumes, but a sound during sleep is not guaranteed.

How this tool fits the task
