- Moving browser playlists matches them to the server's by id or source and
carries the legacy Xtream maps under the server id; it no longer goes
through the backup format, whose PWA export has no Xtream user data. A
partial move stays on offer.
- User-data batches go out in order, and a re-read keeps entries edited
while it was in flight.
- A keepPayload write keeps its cached copy only when the server replaced
the version its payload came from (new X-Replaced-ETag header).
- 502/503/504 from the proxy count as offline.
- The start-up screen lets the sign-in page through while a token is
required.
- Settings → Server offers a reload after a move.
- The probe detects Electron through RuntimeCapabilitiesService.

A failed start-up probe used to fall back to browser mode, which showed an
empty library while the backend restarted and let new playlists land in the
browser. The browser now remembers the server; without an answer it starts
in server mode, offline, and reloads once the server is back. Settings →
Server shows the backend address instead of the page's.
