- Introduced "Managed" (imported to app storage) vs "Linked" (SAF URI) book logic.
- Disabled Google Drive/Metadata synchronization for Folder-Linked books to respect privacy and storage.

* Updates the feature graphic and includes a note distinguishing the OSS version from the Play Store version.
* Refines the "Open Source Libraries" section to be more structured.
* Moves the main preview image into the `docs` directory.
