sanyi1963bp/Vox-Libris ? reverse-engineered prompt

Build me an Android app called Vox Libris for browsing and reading a local ebook library with text to speech.

I want it to open a read only SQLite catalog of books, match that catalog to the ebook files on the phone, and let me browse a big folder tree fast, even with tens of thousands of books. The app should show a dense file browser, let me sort by columns, search inside books, and open a reader screen where the text and playback controls are together. It should read sentence by sentence with the system TTS, highlight the current sentence, remember the exact place I stopped, and let me continue from there later.

Please include bookmarks, reading stats, a simple reading list, and headset button support for play pause and skipping back a few seconds. It should handle EPUB, TXT, FB2, HTML, MOBI, RTF, PDF text layers, and DOCX, and be able to build its own catalog from file metadata if no database is provided. If you need current Android docs or TTS details, look them up online.
