* feat(EPUB): adapt status bar icon visibility to reader theme
Pass the reader's active isDarkTheme state to EpubReaderSystemUiController to ensure status bar icons automatically switch between light and dark to remain visible against the selected background/page color.
* Implement storage tracking and optimize cache management
This commit introduces a `StorageTracker` to monitor disk usage and implements several optimizations to prevent cache bloat and handle orphaned files.
* refactor: unify book extraction paths and fix cache leaks
- Replaced random UUID and title-based hashing with stable `bookId` for extraction directories across Epub, Mobi, and FB2 parsers.
- Standardized all temporary extraction paths to `cache/imported_file_${bookId}`.
- Updated MainViewModel and MetadataExtractionWorker to provide the mandatory `bookId` during parsing.
- Ensured `clearImportedFileCache` successfully targets the correct directories on book deletion.
- Added a legacy cleanup task in `sweepOrphanedCache` to reclaim storage from old `extracted_epubs` folders.
* fix(pdf): handle NoClassDefFoundError for PdfPasswordException
Updated the PDF loading logic in PdfViewerScreen to catch Throwable
instead of Exception. This prevents the app from crashing when the
underlying pdfium library attempts to throw a PdfPasswordException
that is missing from the runtime classpath (NoClassDefFoundError).
* fix(tts): set language before voice to prevent variant reset
* EpubReaderScreen: increase scroll-hide ignore duration for tap toggles
Increase the threshold for ignoring tap toggles after bars are hidden by scrolling from 250ms to 400ms. This prevents accidental UI toggles caused by "sloppy taps" immediately following a scroll action.
* fix: resolve large bitmap crash on tall PDF pages
- Caps base layer bitmap dimensions to 3000px to prevent GPU texture limit crashes.
- Enables tiled rendering for large pages even at 1x zoom to maintain sharpness.
- Optimizes PdfBitmapPool to support rectangular bitmap allocations.
* Common.kt: ensure unique keys in voice list
* fix: handle ActivityNotFoundException in folder sync screen
* Improve file deletion logic and fix chapter index bounds in epub reader

This resolves a WebViewMethodCalledOnWrongThreadViolation in vertical mode that was preventing chapter chunks from loading beyond the initial viewport.
* Added realistic page turn animation option in epub pagination mode
* Added volume key navigation support for paginated render mode and added page turn animation to "tap to change page" and "volume button to change page"
docs: Revamp README and add APK naming convention
This commit introduces a complete overhaul of the `README.md` to improve project presentation. Key changes include:
* Adds a new header with the app icon and a Google Play badge.
* 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.
Additionally, the `app/build.gradle.kts` file is updated to configure a standardized naming convention for output APK files, including flavor, version, and build type.
* refactor copyright headers and fix README icon alignment
This commit introduces two main changes across the codebase:
The `spotless/copyright.kt` template have been updated for consistency:
* The author name is simplified from "Episteme Authors" to "Episteme".
* The contact email prefix is shortened from "Electronic mail:" to "mail:".
Second, the `README.md` file is adjusted to correct the vertical alignment of the app icon with the project title.
