/**
* GOA shop pay popup public pay-template + payto (no merchant secrets).
* QR: white modules, centered official qr-logo (DD 90).
* GOA shop pay popup public only (no merchant secrets).
* Flow: POST templates/{id} taler://pay/… + payto links.
*
* QR display matches taler-merchant-webui QR_Taler
* (@gnu-taler/web-util QR.tsx): animated #0042B3 conic ring + qr-logo.svg.
* Uses qrcode-generator (same lib as webui) via global QRCode if present,
* else falls back to canvas from qrcode.min.js (davidshimjs).
