Add a user-selectable playback mode stored in user_settings:
- 'stream' (default): /api/audio-stream starts playing within seconds,
saves to MinIO concurrently — low latency
- 'generate': queue runner task, poll until full audio is ready in
MinIO, then play via presigned URL — legacy behaviour
UI toggles in two places:
- AudioPlayer idle pill: compact '· Stream / · Generate' inline next
to voice name and estimated duration
- ListeningMode controls row: pill alongside Auto, Announce, Sleep;
disabled and grayed out for CF AI voices (batch-only, no streaming)
startPlayback() now branches on audioStore.audioMode for non-CF AI
voices; generate mode uses the same runner task + progress bar flow
as CF AI but without the preview clip.
PocketBase: audio_mode text field added to user_settings on
pb.libnovel.cc (live) and in pb-init-v3.sh (create block +
add_field migration line).
