Fish-Speech clones from the app's own saved WAV library but was missing from
the set of backends populated with those voices, so the UI probed the Fish
server for a voice-listing endpoint it does not have, showed "Fetched 0
voices" and left the engine unusable despite being healthy. It now reports
the full library (218 voices).
Also adds a Fish-only panel listing all 49 documented emotion tags with
click-to-insert and a multi-emotion example, and corrects the backend's
advertised capabilities: it was flagged style_aware with "emotion markers are
honoured per request", but measurement shows a reference clip's in-context
prosody overwhelms inline tags (10x loudness spread across emotions without a
reference, 1.2x with one). It is now described by what it does well:
deterministic, byte-reproducible cloning.

The emotion quick-pickers added in 1.20.5 guarded with
`typeof REH_EMOTIONS === 'undefined'`, but REH_EMOTIONS is a const declared
later in the bundle's single shared scope — `typeof` on a const in its
temporal dead zone throws instead of returning "undefined", which aborted
top-level initialization for every module bundled after tts-preview.js.
The pickers now read window.REH_EMOTIONS on a deferred macrotask.
Also: emotion instructions are now always built in English (spoken text and
the native-accent clause stay in the book's language), which controlled A/B
testing showed produces a far cleaner prosodic gradient from Qwen3-TTS; and
Fish-Speech now receives temperature/top_p/repetition_penalty, which it was
the only backend never to have forwarded.

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.

Introduces the new Studio section (Source -> Characters -> Voices ->
Perform & Export) that reuses the existing Read Aloud/Library/Script
Rehearsal code via DOM reparenting instead of duplicating it, and rolls up
a long tail of bugs found while producing a real audiobook through it:
umlaut-eating name sanitizers, a voice picker that mispositioned itself and
capped results at 60, PDF pagination silently breaking on trimmed \f
markers, a race letting stale audio keep playing after a new line was
clicked, an alias-overlap bug that could silently redirect a voice/image
save onto the wrong character, voice design failing outright during brief
TTS backend restarts instead of retrying, sparse cast entries defaulting to
English/wrong gender, and a reassigned voice never reaching an already-open
Stage session or invalidating its cached audio. Also adds a persistent
per-line audio cache, audiobook export browsing/download, and an inline
voice-design prompt editor. Full details in CHANGELOG.md.

Replaces the horizontal avatar strip above the transport bar with a
sidebar next to the script page, reusing Read Aloud's Casting sidebar
classes (.ab-cv-side/.ab-char-item) directly instead of a separate
look. Same collapse-to-avatars control, now shows each character's
line count, and clicking a character scrolls the script to their
first line. Removed the CSS/HTML this replaces.

Server logs showed /api/analyze-characters succeeding on every attempt
but /api/voice-design never once being called - the bulk voice-design
loop accessed rehState.cast[sp].voice unguarded right after that
(multi-second, for a large cast) request resolved. Any cast-entry
change during that window threw an uncaught TypeError, silently
killing the whole run with no toast, no further requests, and the
button stuck disabled. Guarded the access and wrapped the remaining
flow in try/catch/finally so failures are visible and the UI always
resets.

- Add a 6-stage pipeline stepper (Source -> Cast Audiobook -> Cast Characters
-> Script Rehearser -> Generate MP3s -> Audiobook) with direct, non-destructive
jumps between stages and a prominent guided-tour look
- Split PDF import into an explicit "load" then "Extract Text" step, with
in-browser OCR (Tesseract.js, vendored) to recover chapter headlines baked
into a PDF as images instead of real text
- Fix casting feed silently merging pages after leaving/returning: segments
now carry their own page number instead of re-guessing it from text
- Fix excessive "Unknown" speaker attribution: restore the attribution LLM's
output token budget, which had been cut roughly in half and was truncating
dialogue-dense passages
- Fix Theater Play library cards failing to open (dead pre-migration
IndexedDB API calls, missing section navigation)
- Fix bulk "Set tag" wiping a voice's existing tags instead of adding to them
- Start merging Casting's feed with Script Rehearser's Stage UI: collapsible
character sidebar, shared "paper" page styling, inline text editing
- Fix a performance regression from that merge (per-row listeners on every
redraw) by moving to event delegation
- Various layout/clutter fixes: hide reader chrome until a document is
loaded, collapse secondary settings by default, fix overlapping toolbar
icons, fix duplicate "opening" notifications

- Casting completion auto-saves to Rehearser IndexedDB (same format
as script rehearsals). Manual speaker corrections in the cast view
debounce-save after 1.5s.
- rehId tracked across session (stored in localStorage draft) so
updates go to the same record instead of creating duplicates.
- Voice assignments made in Script Rehearser survive an auto-update:
only script text and emotions are overwritten; voice/instruct/soul
are merged from the existing record.
- "Edit in Rehearser" button in the completed cast footer opens the
saved record directly in Script Rehearser, ready for voice casting.
- Expose rehDbGetById + rehLoadRecord globally from rehearser.js.

Restructure the sidebar into Voices / Speak / Setup groups and fuse the
Read Aloud and Script Rehearser features into one workspace:
- New combined Library section (Books · Theater Plays · Characters/Cast)
with cross-links (Rehearse a book, Read Aloud a play).
- Character tags like voice tags: one record, many productions, reusable
across books/scripts; seeded with origin book, editable in the editor.
- Shared cast resolution: opening a production fills empty cast slots from
the character roster (matched by book OR tag); voice choices written back
on save. Productions joined by normalized title (prodKey).
- Tags nav group for voices (distinct tags + counts, Cloned/Designed/Fav).
- Fold standalone Characters into Library; Read Aloud now a single entry.

When a PDF audiobook is cast and saved to the Rehearser, page breaks now
carry the source PDF page number. In the Stage view each divider renders
as "— Page N —" instead of the generic "— Page break —".
Implementation:
- audiobook.js: `audiobookBuildScript()` encodes the page number in the
form-feed line (\fN instead of bare \f) at each page boundary.
- rehearser-parse.js: `parseScript()` now matches `line.startsWith('\f')`
and extracts the trailing page number into `line.page`.
- rehearser.js: `buildScriptPage()` renders "— Page N —" when `line.page`
is set; `toScript()` round-trips the number back (\fN) so it survives
save/reload; `importPDFScript()` also encodes page numbers (\f<pageIdx+1>)
when importing screenplay PDFs directly.

- Character sheets: stop sending the dead localhost:11434 default; fall back to
the server's configured llm_url so extraction uses the same working LLM.
- Audiobook casting: hoist highlightText to module scope so the "Review & cast"
manual-correction preview renders its segment rows again.
- Stage: unify narrator/dialog font size, add A-/A+ play text-size control
(scales A4 + paginated views), and make the cast chip list collapsible.

Add a persistent, book-scoped Character Library (new Characters section,
IndexedDB) that auto-fills from Character-sheet analysis with editable cards.
Enrich extraction with six narrative fields (backstory, relationships,
motivation, fears, mannerisms, voice/speech) plus the greyscale Good↔Evil
alignment bar, arc arrow, and 5-area Deep Analysis. Add ⋯ separators between
non-contiguous passages in Recast unknown, and harden dialogue attribution
against hallucination with same-language emotion tags.

Storage: IndexedDB ('reh-library' DB, 'rehearsals' store).
Blobs (recorded mic audio) stored natively; no base64 overhead.
Library panel (Phase 1):
- List of saved rehearsals sorted by last update
- Each row: character-colour avatars, title, progress bar,
line count, recorded-clip count, date
- Active record highlighted in accent colour
- Open / Export .reh / Delete per-row buttons
- Import .reh button at the top
Transport bar (Phase 3):
- Save button (updates existing record if savedId set, else creates new)
- Export button (downloads current state as .reh JSON file)
Phase 4 (session complete):
- Save to library and Export .reh buttons
Data format (.reh file):
- JSON with version=1, title, script text, cast map, backend, lineIndex
- clips serialized with audio as base64 strings (mime + b64 fields)
- clipsFromJson restores Blob objects on import
Behaviour:
- Parsing a brand-new script resets savedId → safe to save as new record
- loadRecord() restores script, cast, lineIndex, clips and jumps to Phase 2
- renderLibraryList() called on init, after save, after delete, after import
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- A4 paper page (white, serif font, shadow) renders the full script at once
so you can read ahead while rehearsing
- Each dialog block shows: character avatar (voice library photo or initial
letter), character name in their colour, TTS/Me badge, and dialog text
- Active line gets a blue left-border highlight and auto-scrolls into view
- Transport bar (sticky, above the script):
- Cast strip: all character avatars at a glance
- ⏮ Prev / ▶ Play all / ⏹ Stop / ⏭ Next / 🔁 Repeat
- Progress bar + line counter
- Auto-play: TTS lines synthesize, play, auto-advance; 'me' lines pause
and slide up a sticky recording overlay at the bottom of the page
- Recording overlay shows the line to speak, oscilloscope + meter,
Record / Stop / Keep & continue / Re-record / Skip
- voice-library.js now exports window._voices so the rehearser can resolve
voice IDs to has_picture flags and fetch /api/voice/picture/{id}

## 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
