4grayandClaude Fable 5 dded17010d fix(playback): keep the display awake while built-in players play video (#1405)
* fix(playback): keep the display awake while built-in players play video

Closes #1095. The renderer tracks every playing <video> through
document-level capture listeners (element-level release listeners catch
the detached-element pause on component teardown) and, while any video
is playing and the document is visible, holds a display-sleep lock:
a main-process powerSaveBlocker over IPC in Electron — reliable on
Linux where Chromium's own video wake lock depends on DE D-Bus
inhibitors — and the Screen Wake Lock API in the PWA. The vote is
auto-cleared when the renderer reloads or dies. Radio's <audio>
deliberately never blocks display sleep; embedded MPV and external
MPV/VLC already manage their own inhibition.

* fix(playback): withdraw the keep-awake vote when the renderer crashes

A crash emits render-process-gone while the WebContents object stays
alive, so the destroyed listener alone missed it: without a follow-up
reload the display stayed pinned awake. Review finding by Codex.

* fix(playback): keep the display lock for picture-in-picture playback

Minimizing the window hides the document but leaves the PiP surface on
screen, so the visibility gate was releasing the lock mid-watch. A
tracked playing video that owns document.pictureInPictureElement now
counts as visible playback, and PiP enter/leave events resynchronize
the gate. Review finding by Codex.

* fix(playback): re-evaluate the wake lock after a rejection masked a state change

In the PWA path a hidden-visible round-trip (or pause/resume) while
wakeLock.request() was pending got swallowed by the in-flight guard; if
that request then rejected, only the flag was cleared and a continuously
playing visible video sat without a wake lock until the next unrelated
event. State changes arriving mid-flight now queue one re-evaluation on
rejection; permanent denials still don't loop because nothing queues a
retry without a fresh interleaved change. Review finding by Codex.

* docs(playback): mirror the display-sleep contract into AGENTS.md

AGENTS.md carries its own playback sections (radio, shared controls,
PiP), so the keep-awake contract belongs there too. Review finding by
Codex.

The screen no longer dims or goes to sleep while a built-in player is playing video — including on Linux desktops, where the system idle timer used to ignore the app. Pausing or stopping hands control back to the system immediately, and radio playback deliberately leaves the display free to sleep. Works in both the desktop app and the PWA.
