- UPLOAD_DIR moves to the USB drive; reads fall back to UPLOAD_BACKUP_DIR on the
ytplayer-data volume, and while the drive is offline new uploads land there
- scripts/ops/uploads-backup.sh (homelab cron, 03:30) copies both ways, never
deletes; the server removes a deleted upload from both places
- /api/channel resolves a bare channel name ('Artist - Topic') to its id via a
search, and the client falls back to the channel name for old saved entries
