+-- Migration: Add access_tier to users table
+-- Run this on production before deploying the new mana-auth version.
+-- After this migration, run `drizzle-kit push` or redeploy mana-auth.

+-- Alternatively, just run `pnpm db:push` from services/mana-auth/ which
+-- will apply the schema change automatically via Drizzle Kit.
