- Create backend/services/image_storage.py with 4 core functions:
- sanitize_filename(): remove unsafe chars, limit to 255 chars, convert to lowercase
- get_unique_filename(): handle collisions with UUID suffix (format: {name}_{uuid8}_{variant}.jpg)
- ensure_image_directories(): create /images/ root and category subdirs on startup
- save_image(): save bytes to /images/{category}/{filename}, returns relative path
- Create comprehensive test suite (22 tests) covering all functionality
- Integrate ensure_image_directories() into FastAPI startup event
- Directory structure: /images/{category}/{filename}
- Collision handling: auto-suffix with UUID if filename exists
- All tests passing, pathlib.Path for safe operations
