  * Seed script for Port Nimara CRM.

- *        - Marina Azzurra
- *        - Harbor Royale
+ *   1. Create the operational ports (idempotent):

+ *        - Port Amador (secondary, kept for multi-tenant isolation tests
+ *                       and as scaffolding for a future Panama install)
  *   2. Create 5 system roles with full permission maps
  *   3. Create the super admin user profile placeholder (matt@portnimara.com)
  *   4. For each port, call `seedPortData(portId, portSlug)` from seed-data.ts
  *      to produce the realistic multi-cardinality fixture
- *      (berths, clients, companies, yachts, memberships, interests,
- *      reservations, ownership-transfer history).

  *   5. Print a summary.
