Deploy Ladill QR Plus / deploy (push) Successful in 2m2s
Create was making three sequential public HTTPS billing calls (~400ms each) while holding a DB transaction open for image generation. Use loopback DNS forcing, cache balances briefly, return balance from debit, regenerate images only when style changes, and keep remote work outside the DB transaction.
