- What's next is the server's: state.advance counts down (10 s) when the
media finishes with an Up next item first, holds while its performer or
warm source is gone, and sets queuePlay at its end; cancel is shared, a
seek or swap ends it; the server skips items nobody can put up. Shared
rules in core whats_next.dart; the app's janitor, per-screen countdown
and end-of-episode card are gone.
- The continuation (next Jellyfin episode, next file of a local show
with its gaps) is an auto item under "Continues with", prepared like
Up next's first item.
- Watch tracking by time In (D3): only time played while this viewer is
in counts; away, paused, held, jumps and stalls never do (P7, P9).
WatchTracker + device WatchHistory (files, links); Jellyfin progress
reads the same watch; records are the AniList seam.
- A server restart no longer loses what played: apps hold their media
and one offers it back (swap.restore, first offer wins), Up next is
re-added, the source re-feeds, and the watch carries on.

Server and core: version ranges on both sides with a coded refusal; a
client id maps to the same member and token for the server's life; a
drop is `gone` for a 10-minute grace keeping ready, presence, queue
items, relay and avatar; `bye` leaves at once; ordered takeover (seq,
replaced/stale); presence joining/in/away/gone with one PresencePolicy;
joiners never pause playback and hold a held gate at most ~15 s;
state.hold; feed ids, seq and replay; the relay lives through its
source's grace and continues on re-dial; queue `by` lasting, auto
items and cancel; MediaRef carried; client ids never logged.
App: persisted client id and seq; Connection with unstable/lost/
replaced states, backoff with jitter, no lost/back pair per flap; a drop
keeps the session (state, player, media, relay source); presence in the
strip and members card; sit out = away intent; feed matched by id;
auto sit-out (idle when not playing, minimised for a while; never when
alone) replaces auto-unready; bye on close and Leave, not on update
restart; relay source re-dials through its grace.
