+ * Migration: 2026-05-24 — Rename @tcgvault.com user emails to @deckhearth.com

+ * Part of the `pick-a-name` convoy. Renames every `users.email` row matching
+ * `%@tcgvault.com` to the `@deckhearth.com` equivalent (admin + alice + bob,
+ * plus any other accidentally-`@tcgvault.com` users if they exist).
+ *

+ *
+ * Usage:
+ *   node scripts/migrations/2026-05-24-rename-admin-email.js
+ *
+ * Required env: POSTGRES_URL (read from .env.local).
+ *
+ * Safety: the UPDATE uses REPLACE() so emails like `admin@tcgvault.com`
+ * become `admin@deckhearth.com`. The `users.email` UNIQUE constraint will
+ * fail loudly if a row with the target email already exists — which is the
+ * correct behavior (do NOT silently overwrite). If you see the constraint
+ * violation, inspect the DB manually before retrying.
