  localStorage and shareable ?view=?density= URL params (URL wins)
- table view: sortable columns (name, rating, reviews), new sort options
  name_asc/name_desc/recently_updated (backend enum + handler)
- live debounced search, removable filter chips, '/' focuses search
- virtualization via @tanstack/react-virtual for table and rows views
- profile sync: users.preferences jsonb + GET/PUT /api/auth/me/preferences;
  preference precedence URL > server profile > localStorage > default
