/* deltaecho.cn 报名中心（/shop/ 及其下实训营、剧本杀、下单、订单与支付、用户协议共 6 页）的版式，2026-10 WP5 换成官网第二版视觉。
   颜色、字体、字号档位、缎面与细网格全部来自 /assets/brand/static.css（构建时由 build.py 从 engineering/design-tokens 拷来，与官网同一套），
   这里只按页面结构与 shop.js 生成的结构排版；脚本生成的类名（.choice .alert .pay-btn .qr-box .code-box .kv .summary …）
   一个不改，scripts/check-shop.py 会核对它们在本文件里都有样式。后台 /shop/admin/ 10-05 起是应用外壳，样式在 admin.css 与 ui.css，不用本文件。页头页脚照官网子页面（website-next 的 PageNav 与 Footer）。
   动效只动 transform 与 opacity；大面积柔光用径向渐变，不用 filter: blur（09-27 iPhone 卡顿的教训）。
   /about/、/contact/ 仍用 cn-pages.css，不受本文件影响。 */
