- Outfit font for UI, JetBrains Mono for code/URLs
- Custom nav with SVG icons and active-state highlighting
- Pill badges with colored status dots
- Uppercase letter-spaced table headers
- Stat cards on replica detail page
- h3 section headings with extending rule line
- Refined dialog/modal styling with blur backdrop
- Terminal-style SSE log stream

Allows promoting any replica to master with zero document re-downloads.
The sync_map rebuild uses existing DB data only — pure in-memory join.
Changes:
- app/sync/promote.py: preflight() checks (doc count, sync lock, ack
warnings) and promote() transaction (pause scheduler, rebuild all
sync_maps, create old-master replica, swap settings, resume scheduler)
- app/api/master.py: GET /api/master/promote/{id}/preflight (dry run)
and POST /api/master/promote/{id} (execute)
- app/models.py: add promoted_from_master bool field to Replica
- app/database.py: idempotent ALTER TABLE migration for new column
- app/main.py: register master router
- app/templates/replica_detail.html: "Promote to Master" button +
dialog with pre-flight summary, 3-card stats, ack checkboxes, spinner
- app/ui/routes.py: flash query param on dashboard route
- app/templates/dashboard.html: blue info banner for post-promotion flash
