- New ParticipantLimits component in FormField.tsx (reusable)
- Used in both Open Day settings and MC editor — identical layout
- Open Day: event-level min/max (DB migration 15)
- MC: per-event min/max (JSON fields)
- Public: waiting list when full, spots counter, amber success modal
Multi-session master classes are a series — once the first session
passes, the group has started and registration closes. Changed all
MC date logic from "latest slot" / "any future slot" to "earliest slot":
- DashboardSummary: upcoming = earliest slot >= today
- McRegistrationsTab: archive = earliest slot < today
- AddBookingModal: only show MCs where earliest slot >= today
- Public MasterClasses: isUpcoming checks earliest slot
- isUpcoming() now checks startTime, not just date — past events hide after they start
- Cards without images get a gradient placeholder instead of collapsing to 0 height
- Merge two Reveal wrappers into one to prevent empty Reveal stuck at opacity 0
- Use flex layout with justify-center so single cards are centered
