-/**
- * db-extras.ts — Run all custom SQL migrations that Prisma doesn't manage.
- *
- * This script runs after `prisma db push` / `prisma migrate deploy` to set up
- * tables and functions that need raw SQL (UNLOGGED tables, custom functions, etc.).
- *
- * Usage: bun run db:extras
- *
- * To add new custom migrations:
- *   1. Create a .sql file in prisma/migrations/
- *   2. Add the filename to the EXTRAS array below
