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.
Utility QR types only (URL, WiFi, link list, business, app download) with
SSO, Billing API integration, public /q resolver, and qr-plus:import for
platform migration. vCard and commerce types stay on the platform.
