Playtest feedback round 2:
- blindtest DJ can now be anyone incl. the track's contributor (pickDj only
excludes bots) — no more "immunity" for whoever isn't picked
- blindtest rounds last 90s (longer listen + typing)
- per-player volume slider (persisted), YT player setVolume + origin/enablejsapi
- theme switcher (light/dark/system) on home + room header
- clock sync: clients estimate the server-clock offset (time:sync) so the
countdown is identical across devices (was off by each device's clock skew);
also used for blindtest media sync
Note on duplicates: anti-repeat is per room code (quiz_played) — it works when
you replay in the SAME room, but a new room starts fresh. Verified e2e: two
chained games in one room share 0 questions.
Verified: typecheck 4/4, lint 4/4, 24 server tests, web build; e2e dedup (0
overlap) and clock/DJ behavior.
