 ### Changed
+- **Audiobook cast export extraction.** Markdown serialization and legacy page-stamping migration now live in
+  `audiobook-cast.js`, leaving the live casting workflow in `audiobook.js` and preserving the same global helpers.
 - **Rehearser training extraction.** Transcript normalization, LCS matching, and word-level comparison now live in
   `rehearser-train.js`; recording and state-machine wiring remain behavior-compatible in `rehearser.js`.
 - **Rehearser cast-controls extraction.** Cast view switching, sorting, filtering, and their guarded event wiring now

 - [x] Extract Rehearser library persistence and IndexedDB migration into `rehearser-library.js`.
 - [ ] Extract Audiobook parsing and casting.
 - [x] Extract Audiobook parsing primitives and speaker-heuristic constants into `audiobook-parse.js`.
+- [x] Extract Audiobook cast serialization and page-stamping helpers into `audiobook-cast.js`.
 - [ ] Split `style.css` by feature.
 - [ ] Do not migrate to TypeScript or rewrite the frontend until behavior is covered by tests.
