Fish-Speech emotion tags were silently ignored on non-English books: per-line
emotions are LLM-generated in the book's own language, but Fish-Speech only
recognizes English [tag] markers, and a double-tagging bug was stacking a
broken server-derived tag on top of the client's own. Added a DE->EN
translation table and removed the double-tagging. Also wires the existing
book-profile context and race_species field into character portrait prompts
(previously only used for voice design), adds a recast-until-threshold loop
for casting, and adds backend-aware emotion quick-picks to Read Aloud, Try a
Voice, and Conversation.

Voice consistency:
- Read back each voice's pinned seed (Seed Finder / Batch Seeds) on every
generation. The seed was saved to voice metadata but only ever read by the
Seed Finder's own benchmark path, so all per-voice seed pinning was inert.
- Stop coercing the "voice_design_playback" stability profile back to
"voice_clone". The pseudo-backend key isn't a real routing target, so the
backend-name normalizer silently rewrote it — reintroducing the hardcoded
seed:0 that profile exists to avoid, overriding every per-voice pin.
- Apply the accent clause on every line, not just at voice-creation time,
and reorder the instruct so emotion leads and accent trails (Qwen3-TTS
doesn't reliably follow multiple conflicting instructions).
- Pass an explicit language to Voice Design instead of leaving it on "Auto".
Audio effects:
- Add a limiter after compressor makeup gain. Makeup gain pushed peaks to
~1.9, and the final hard clip turned that into broadband distortion that
swamped the rest of the chain.
- Cascade highpass/lowpass 3 stages each (~18 dB/octave). Single-pole
filters were too gentle to band-limit speech audibly.
- Add a Bandpass control and wire it into the Telephone/Radio presets —
compression alone never sounded like a phone; band-limiting is the
defining trait.
Persona / Try It Out:
- Disable "Apply character persona" with an explanatory tooltip when the
voice has no persona saved, and error clearly server-side instead of
silently no-op'ing. Persona is typed manually per voice, never auto-filled.
- Stop dropping applyPersona in the chunked generation path (>200 chars).
- Populate the Voice Design dropdown from the user's own library rather than
filtering the engine's discovery list, which never contains custom voices.
Navigation and library:
- Use pushState instead of replaceState so browser Back/Forward step through
in-app navigation instead of leaving the app entirely.
- Show real dialogue line counts in the character sidebar instead of the
capped reference-quote count (which showed a misleading uniform "12").
Also fixes a crash in /api/transcribe-bytes that referenced an undefined
source_id in its cleanup path.

- Sidebar collapses to a 56px icon rail; hovering flies the full menu out as
an overlay (icons + titles/nested items). Language picker moved to Settings.
- Unify settings collapsibles to the app's standard card-collapse style:
Conversation, Read Aloud (drag-&-drop now inside), Try It Out, Casting panel.
- Read Aloud: reordered (settings → toolbar → document → transport/synth) and
the document fits the viewport height so controls below stay visible; remove
the redundant My Books card (lives in Library → Books).
- Conversation: stacked full-width config, fills viewport height; fix
intermittent webm decode in hands-free mode (recorder restarts cleanly,
in-browser WAV encode); barge-in via Live agent.
- Fix casting feed overflow that pushed the sidebar off-screen.

Exposes the `speed` parameter (0.5–2.0) on the TTS `/v1/audio/speech`
request so audio is generated at the target tempo natively via the
faster-qwen3-tts backend rather than post-processing.
- Backend: `/api/tts-preview` now extracts and forwards a `speed`
override (clamped 0.1–4.0) through the same extra-params mechanism
already used for seed/temperature; backends that reject it fall back
cleanly via `_post_tts_with_fallback`.
- Try it out: "Native Speed" number input (0.5–2, step 0.05) added to
the text card; value persists in localStorage per browser; passed as
`extra` through `createTtsAudioSource` and `generateChunkedTts`.
- Read aloud: "Native Speed" control added to the generation controls
row alongside seed/temperature; included in `readerGenParams()` and
saved/restored with library documents (each book tracks its own speed).

## Script Rehearser (new feature)
- New section s-rehearser.html + rehearser.js + nav/loader wiring
- Phase 1: paste/upload script (.txt), auto-detect characters from
'CHARACTER: dialog' or ALL-CAPS screenplay format
- Phase 2: assign a TTS voice per character, or mark 'I play this'
- Phase 3: step-through rehearsal — synthesizes other characters via TTS,
shows level-meter + oscilloscope for your own lines, records them from mic
- Phase 4: session summary with per-line audio playback + download
## Connect Apps
- Removed duplicate standalone MCP/speak/hotkey full-width cards
- Kept the integration-grid cards (they use the real server URL from JS)
- Added Global Hotkey Daemon as a proper integration card with snippet-hotkey
populated by integrations.js (uses proxyBase URL dynamically)
## About page
- GET /api/changelog endpoint reads CHANGELOG.md and returns it as text
- Collapsible 'Changelog' <details> card fetches and displays it lazily
## Try It Out
- Reorganised into three cards: Voice & backend / Text to synthesize / Generate
- Backend help panel moved below the voice row (not in the same flex row)
- Style instruction field gains a dynamic badge ('style-aware ✓' / 'weak style')
and a yellow warning when a non-style-aware backend is selected while the
field is filled — wired to both backend-select change and input events

- Rename "LLMs" section to "Engines" with brain icon
- Add three sub-pages (Language Models / Speech to Text / Text to Speech) following the same nav-tree pattern as Settings and My Voices
- Rewrite s-llms.html: three s-engines-page divs, docker container grids (dc-grid-tts, dc-grid-stt), VibeVoice card in TTS section, static cloud API cards per category
- Add navEnginesCat() and applyEnginesPage() to nav.js; engines tree open/close in showSection()
- Remove obsolete initLlmCatTabs IIFE; fix dc-refresh-btn from ID to class-based querySelectorAll
- Make integration cards in Connect Apps collapsible (collapsed by default) with favicon/icon prepended to h3
- Unify all Engines card grids to minmax(380px, 1fr) so local, docker, and cloud cards are the same width
- Add s-engines-page CSS (display:none / is-active:flex)

- New s-performance section: dedicated Benchmark nav entry with run form,
per-session results table, RTF trend badge (faster/slower/stable), SVG
sparkline chart, and a History card backed by localStorage (last 50 sessions)
- Performance tab removed from Try It Out; element IDs unchanged so JS works
- renderIntegrationSnippets: adds Python MCP server + Claude Code .mcp.json
config snippets to the Connect Apps page (integration-card-wide styling)
- Save handler: persists all Captures settings fields (stt_language,
stt_preferred_backend, auto_refine, refine_model, refine_* toggles,
captures_default_voice) alongside existing settings
- CSS: integration-card-wide accent border, benchmark history rows, trend
badges, sparkline wrapper, bench-history-toolbar

New TTS backend: Kokoro FastAPI (82M) — OpenAI-compatible, 11 built-in
voices, only shows when server is reachable (~300 MB CPU, ~0.1× RTF).
New STT backends in Transcribe dropdown: faster-whisper (CTranslate2 GPU,
~70× RT, 1.5 GB VRAM), whisper.cpp (CPU/CUDA, ~8–15× RT, ~1 GB RAM),
Groq Whisper (fastest cloud, free 2 000 req/day, key shared with Groq LLM).
Backend help panels now show ⚡ speed · ⏰ latency · ⭐ quality · 💾 RAM
metric chips for all TTS and STT backends.
Active Docker Stack cards also get per-container metric chips.
AI Backends section: "Use as STT" / "Use as TTS" one-click buttons on
faster-whisper, whisper.cpp, and Kokoro cards apply URLs to Settings
without leaving the page. Groq Whisper card notes the shared key path.
Settings: Kokoro URL in TTS cluster; faster-whisper URL, whisper.cpp URL,
Groq API key in STT cluster; quick-fill buttons for all local STT engines.

- Substitute 0.0.0.0 → host.docker.internal before probing (0.0.0.0 not routable from Docker)
- Add /api/local-containers, /api/probe-url, start/stop/restart endpoints to server.py
- Rewrite AI Backends section into Local / Online API categories with Docker stack grid,
local service cards (LLM/STT/TTS) with icons and editable URL inputs, online cloud API cards
- Add bind mounts for static/ and server.py so changes take effect without image rebuild
- Add dc-grid, llm-local-grid CSS with uniform minmax(310px,1fr) card layout
- Fix VOICE_HOST_DIR default via .env so voice folders survive container recreation

- New light UI: fixed 220px sidebar, single scrolling page, 8 named sections
- Static files split by concern: style.css, app.js, loader.js, nav.js
- Each page section is its own partial in static/sections/s-*.html
- loader.js fetches all section partials in parallel, then loads app.js and nav.js
- All original functionality, element IDs, and API endpoints preserved
