This beta focuses on stability and QA follow-up fixes.
- Fixed dark mode persistence so theme preference now applies correctly on reload.
- Fixed photo-library post flow that could freeze when selecting and submitting an image.
- Improved timestamp handling to avoid incorrect future-date rendering.
- Hardened image public URL generation to fail safely when env configuration is missing/malformed.
- Added delete support for own posts/comments to make QA cleanup and content management easier.
