Context-specific upload policy
Choose readable format families rather than typing MIME values. Activity, replies, messages, profiles, and albums each have appropriate limits and browser guidance, with independent REST validation.
Privacy-first albums
- Public, members, connections, and private audiences
- Profile privacy as an outer boundary
- Role and member-type creation rules
- Immediate, new-member, or all-member moderation
- Owner editing and deletion
- Guarded storage and audience-checked delivery URLs
