   AIDC 产品页 —— /products 与 /products/*（public/products.html、public/products/*.html）。
   由 scripts/build-products.mjs 生成；这里只写 pd- 开头的样式。
   外层 .hd.pd：标题、段落、FAQ、收尾沿用 home.css 的 .hd-*；
   子导航、分格流程、编号步骤、代码块复用 developer.css 的 dv-*（页面同时加载 developer.css）。
   首屏尺寸与 semantic.css 的 .sm-hero 保持一致；颜色一律用 site.css 的令牌。
   面分层（docs/site-design.md）：卡片是灰面、不描边；灰面里的胶囊与行换成白色；状态用浅色底的胶囊。
