- Create Profile.tsx for viewing other users (highlights + writings only)
- Profile uses useStoreTimeline for instant cache-first display
- Background fetches populate event store non-blocking
- Extract toBlogPostPreview helper for reuse
- Simplify Me.tsx to only handle own profile (/me routes)
- Remove isOwnProfile branching and cached data logic from Me
- Update Bookmarks.tsx to render Profile for /p/ routes
- Keep code DRY and files under 210 lines
