- Route now logs every synthesis request (char count, voice, speed)
- Route logs char count + text preview when the 8000-char limit is hit
- Route logs empty audio with preview (helps spot no-chunk-produced edge case)
- Route logs success with byte count and duration
- Kokoro synthesise() logs per-call: samples produced, elapsed, chars/s
- Kokoro synthesise() logs warning when zero audio chunks returned with preview
- Kokoro synthesise() catches and logs pipeline-internal errors with preview
- Frontend: console.warn now includes char count + 80-char preview on failure and retry

- On first load: model runs online (downloads .pt files), then stores the
current HF commit SHA to /data/kokoro_commit_hash.txt and switches the
process to offline mode (HF_HUB_OFFLINE) for all future requests
- On subsequent restarts: presence of the commit file triggers offline mode
before the pipeline loads, skipping all HuggingFace network validation
- Daily at 03:00 UTC: scheduler temporarily lifts offline mode, fetches the
latest commit SHA from HF, and only reloads the pipeline if the model has
actually changed — then restores offline mode
- Removed HF_HUB_OFFLINE from docker-compose.yml; behaviour is now automatic
and not a hoster/user concern

- ChatView: listen mode toggle (auto-reads new responses via TTS), volume popup
with range slider persisted per-device in localStorage via GainNode
- useVoiceAudio: shared module-level _volume ref with localStorage persistence,
GainNode for volume control, exported setVoiceVolume()
- tts.py: pre-warm all Kokoro voices at pipeline load to eliminate HuggingFace
HEAD requests at synthesis time (reduces TTS latency)
- BriefingView: discuss article button now auto-sends instead of just filling input;
prompt capped to 15 sentences; send() accepts optional overrideText
- llm.py: instruct LLM not to proactively search notes or comment on note absence

Add voice blend support to TTS pipeline and settings UI. Users can mix
2–5 Kokoro voices with per-voice weight sliders; the blended style tensor
replaces the single voice when enabled. Settings persist as JSON and auto-
load on synthesis when no explicit voice is supplied in the request.

Voice enabled/STT model are now DB-backed (admin settings), not env
vars. Added reload_stt_model()/reload_tts_model() that clear singletons
under lock and re-trigger loading. POST /api/admin/voice/reload triggers
both in background tasks. Settings UI polls /api/voice/status every 2.5s
until models are ready, with spinner feedback.

Replace VOICE_ENABLED env var gate with DB-backed admin setting.
- services/voice_config.py: reads voice_enabled + voice_stt_model from
admin user's settings row (falls back to env var defaults)
- routes/admin.py: GET/PUT /api/admin/voice for admin configuration
- routes/voice.py, services/stt.py, services/tts.py: read enabled/model
from DB via voice_config instead of Config directly
- app.py: always schedule model loaders at startup; they self-gate on
the DB setting so no conditional needed at the call site
- SettingsView.vue: Voice section in Admin → Config tab (enable toggle +
STT model dropdown); user Voice tab now points to admin panel when disabled
No env var required to test — enable via Settings → Admin → Config → Voice.
