Important behaviors

• Managed event types — a parent EventType propagates fields to children (one per team member). Children share the parent's slug under each team-member's profile.
• Booking fields — JSON column stored as a typed Zod array; rendered by the form-builder package. Defaults include name + email; organizers add custom inputs (single-line, paragraph, select, multi-select, phone, ...).
• Period rules — control how far in advance bookings are allowed. Implemented by packages/lib/isOutOfBounds.tsx.
• Seats — seatsPerTimeSlot > 0 activates the seat-based flow handled by packages/features/bookings/lib/handleSeats/.
