# Ship local `supabase/migrations/*.sql` to the prod DB and apply them in
# alphabetical order (= timestamp order given Supabase's filename convention).
#
# Usage:
#   ./scripts/prod/push-migrations.sh                # apply all migrations
#   ./scripts/prod/push-migrations.sh 20260501_foo   # apply only matching files
#
# Migrations should be idempotent (`IF NOT EXISTS` / `OR REPLACE`) — the
# script stops on the first failing statement so you notice drift immediately.
