/**
 * Example Rebase Script
 *
 * Scripts run OUTSIDE the server and need explicit authentication.
 * Use a Service Key (set in .env as REBASE_SERVICE_KEY) to get admin
 * access — similar to a Service Account credential.
 *
 * Usage:
 *   # With local dev server running (`pnpm dev` in another terminal):
 *   npx tsx scripts/example.ts
 *
 *   # With remote backend:
 *   REBASE_URL=https://api.yourdomain.com npx tsx scripts/example.ts
 *
 *   # Service key can also be passed as env var:
 *   REBASE_SERVICE_KEY=<key> REBASE_URL=https://api.yourdomain.com npx tsx scripts/example.ts
 *
 * Generate a service key:
 *   node -e "console.log(require('crypto').randomBytes(48).toString('base64'))"
