- Removed `onProgress` callback from `regenerateChapter` and related functions across `TTS`, `EPUB`, and `PDF` contexts to simplify the chapter regeneration API.
- Updated `AudiobookExportModal` to align with the refined regeneration API, including removing granular chapter progress display and adding a hint about TTS caching behavior.
- Introduced `TTSAudiobookChapter` interface and renamed `ContinuationMergeResult` to `TTSSmartMergeResult` and `PageTurnEstimate` to `TTSPageTurnEstimate` for better type consistency and clarity.
- Applied minor styling adjustments to buttons and listbox components in modals for visual consistency.
- Added `'use client'` directive to several client-side components for Next.js 13+ compatibility.
- Updated Dockerfile build command from `pnpm run build` to `pnpm build`.
- Added Playwright tests to verify backend chapter state after regeneration.
- Offload computationally intensive text matching for real-time highlighting to a dedicated Web Worker, ensuring the main thread remains responsive during playback.
- Implement a new overlay-based highlighting system that renders independently of the PDF's text layer, providing smoother and more reliable visual feedback without interfering with document rendering.
- Introduce a new setting allowing users to enable or disable real-time text highlighting in PDFs, offering personalized control over the reading interface.
- Upgrade the underlying text comparison algorithm to Dice similarity for more accurate and context-aware matching of spoken words to on-screen text, improving synchronization precision.
- Improve sentence boundary detection, especially for quoted dialogue and complex structures, by enhancing the NLP processing logic, leading to a more natural audio-text flow.
introduce configurable smart sentence splitting with persisted state,
UI toggle, and EPUB/PDF contexts that send continuation metadata.
enhance TTS pipeline to merge cross-page sentences, manage carryover,
and trigger visual page changes during playback for smoother narration.
update README with kokoro quick-start guidance, remove the legacy
issues mapping doc, and add deterministic TTS mocks plus sample audio
for Playwright tests.
