Deploy Ladill QR Plus / deploy (push) Failing after 1s
Extract Ladill QR Plus as standalone app at qr.ladill.com.
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.
