Source changelog

- Initial release: Remove watermarks from white-background document images using a pure local Python script. - 4-step semi-automatic workflow: visual region selection, threshold analysis, watermark removal, and verification with auto-retry. - Handles light-colored text overlays, exam paper watermarks, and scanned document contamination. - Region-based removal preferred for minimal text damage; full-image removal supported for scattered watermarks (requires scipy). - Includes detailed troubleshooting and retry guidance for best results. - No API key needed; works entirely offline with only local Python dependencies.
