Render topics as a two-level tree so editing is clearer and limit updates to name/sort while parent selection stays create-only. Keep topic deletion safe with FK cascades and ensure photo tag links are cleaned automatically when a topic is removed.
Add topic editing and deletion flows in the topics admin section with nesting safeguards for two-level hierarchy. Make photo topic assignment immediate on select change so tags are attached without extra confirmation clicks, while keeping inline detach actions.
Introduce a new 'topics' entity with two-level nesting and a many-to-many link to photos. Add topic management in admin and inline AJAX attach/detach controls on photo cards so editors can assign or remove topics without reloading the page.
Let admins manage section names and ordering from the media sidebar without manual DB edits. Add safe section deletion in admin flow and remove the section storage folder after DB cascade cleanup.
