/*
 * Universal checkout stylesheet, contract v1 (UC-1).
 *
 * The ONE platform-owned checkout stylesheet — the same Shopify-style two-column
 * checkout for every shop, lightly branded per shop via CSS custom properties
 * the page shell (universal-checkout.html) sets in an inline <style>:
 *   --brand-primary      — the shop's primary brand color (theme colorScheme)
 *   --brand-primary-text — readable text ON the primary color
 *   --brand-font-heading — heading font stack (theme headingFont)
 *   --brand-font-body    — body font stack (theme bodyFont)
 * Each has a neutral fallback so the page renders fine when a var is absent.
 *
 * Served at /_platform/checkout-v1.css. Framework-free, no build step.
