/* web/storefront/src/theme.css
 *
 * Nordic Home buyer-storefront theme — the shared visual language for all 12
 * buyer screens (A2). This is the STORE identity: warm paper + forest green +
 * Fraunces serif display + Figtree body, strictly distinct from the enterprise
 * console (cool grey + blue + Plus Jakarta). Tokens mirror the design system
 * base (DesignSystem board, "店铺主题 Token · 用户端身份") so a store theme can
 * later be re-skinned from /api/storefront/context by overriding --bo-* on :root.
 *
 * Page-specific layout lives inline in each page; this file carries only the
 * tokens, reset, and the chrome shared verbatim across pages (header, footer,
 * product card, buttons, chips, account nav).
