issue that caused 404 errors for GIF files.
Changes:
- Added new troubleshooting subsection: 'GIFs return 404 but files exist'
- Documented the nginx regex problem and solution
- Included before/after nginx configuration examples
- Explained negative lookahead regex pattern
- Updated Docker image digest to latest version
