lowercase tags, author notes, source URL and private/public visibility
- Central RecipeQuerySet.visible_to() used by every read path; edit only
by owner, delete by owner or admin (visible recipes only)
- Text-based editing: ingredient/step parser with roundtrip and scaling
- Photo upload (JPEG/PNG/WebP/HEIC), re-encoded to WebP without EXIF,
thumbnails, cover image, served only through permission-checked view
- Search across title, description, ingredients, tags; ingredient and tag
filters; "mine" and favourites views
- Admin can delete all recipes of a deactivated user
- Acceptance tests: private recipes unreachable for others and admins
in list, search, tags, favourites, detail, edit, delete and image URLs
