Richard R cb9ca37500 refactor(epub): unify TTS segment planning with canonical windowing 
Consolidate EPUB TTS segment planning around a single canonical windowing model.
Introduce `epub-canonical-window.ts` to provide stable, viewport-independent
segment windows for both playback and sidebar. Refactor segment planning,
prefetching, and playback handoff to use canonical ordinals and keys, ensuring
that segments straddling page breaks are uniquely identified and never replayed
across pages. Update TTSContext, SegmentsSidebar, and related hooks to support
windowed canonical segments and precise ordinal continuity. Extend types and
interfaces to carry canonical segment metadata and windowing context.

Add comprehensive unit tests for canonical window selection, segment
materialization, and cache behavior.

BREAKING CHANGE: EPUB TTS segment planning, playback, and sidebar now rely on
canonical windowing, affecting segment key generation and playback logic.

📄🔊 OpenReader

OpenReader is an open-source, self-host-friendly text-to-speech document reader built with Next.js for EPUB, PDF, TXT, MD, and DOCX with multilingual, synchronized read-along playback.

Previously named OpenReader-WebUI.

Get started in the docs.

✨ Highlights

  • 🧱 Layout-aware PDF parsing with PP-DocLayoutV3 (ONNX) — structured block detection, cross-page stitching, and geometry-based highlighting for precise read-along sync.
  • ⏱️ Word-by-word highlighting via ONNX Whisper alignment through the compute worker control plane (NATS JetStream-backed).
  • ⚡ Segment-based read-along for EPUB, PDF, TXT, MD, and DOCX — sentence-aware TTS with cached audio segments, background preloading, and resumable playback.
  • 🎯 Multi-provider TTS — self-hosted OpenAI-compatible servers (Kokoro-FastAPI, KittenTTS-FastAPI, Orpheus-FastAPI) or cloud APIs (OpenAI, Replicate, DeepInfra).
  • 🌐 Multilingual support — choose a document language for language-aware narration and highlighting. Available languages depend on the configured TTS provider and voice.
  • 🎧 Audiobook export in m4b/mp3 with resumable chapter processing.
  • 🗂️ Flexible backend — embedded SeaweedFS or S3-compatible storage, SQLite or Postgres, server library import, and device sync.
  • 🐳 Self-host friendly — Docker (amd64/arm64), built-in auth/session support, and automatic startup migrations.
