+// File: ticket.go
+//
+// Purpose
+//   Canonical persistence model for tickets as stored in DB,
+//   plus display helpers populated at read time.
+//
+// Responsibilities
+//   - Represents input values for ticket creation
+//   - Stores normalized draw fields for comparison
+//   - Optional fields (bonus, syndicate) use pointer types
+//
+// Notes
+//   - Read-only display fields must not be persisted directly
+//   - TODO: enforce UserID presence once per-user tickets are fully enabled
