SolPay Pro Kit

• Multi-product cart (cart.html + worker.js): server-side catalog pricing, so buyers can't edit prices; stateless order tokens.
• Receipt hook: set WEBHOOK_URL and the worker POSTs a JSON receipt on confirmation. Includes copy-paste examples for email receipts and Google Sheets (Apps Script), and Discord/Slack notifications.
• WooCommerce snippet: a small PHP plugin that shows a Solana Pay USDC QR on the thank-you page and marks the order paid after on-chain confirmation.
• Shopify-alternative buy button for Carrd, Webflow, Squarespace and Ghost embeds.
• Payment dashboard (dashboard.html + /api/payments): recent incoming USDC/SOL with detected references, totals and Solscan links, token-protected.
• The basic kit's checkout.html, GUIDE.md and check-balance.mjs.
