{# trade-pro product detail — cms 产品详情精确对齐重做（Task 12a，重做 10b）。
设计源（唯一权威依据）D:/project/cms/runtimes/astro-site-runtime/src/pages/
[locale]/products/[slug].astro，区块序列逐块对照：
detail-hero（面包屑 + 1.08/0.92 双栏：画廊/标题区，cms 产品名 h2 全页无 h1）
→ product-tabbed（sticky 选项卡：Product Details 正文恒有 + Specifications
参数表有数据才显）→ related-detail（sf-tp-card 卡片网格）→ quote-section
（左联系信息 + 右 CTA/外部表单）。
与 cms 的三处结构决策：
1. 选项卡系统照搬 cms：容器 data-sf-tp-tabbed + .sf-tp-panel/.active 面板 +
尾部内联 <script> 切换（运行时给容器加 sf-tp-tabs-enabled，CSS 只显示
active 面板并隐藏 panel-title）——无 JS 时默认形态即 cms 回退形态：面板
全部平铺可读、panel-title 可见，静态可抓取。
2. 正文不拆表：WordPress 规格表 <table> 直接在 body HTML 里，正文整体作为
Product Details 面板渲染（.sf-tp-product-body rich-body 表格样式：全宽/
发丝框/斑马纹/覆盖内联宽高/单元格 div 净空）；specs 变量有数据时另设
Specifications 面板（干净 spec-table，每行两对键值，从 fields 读）。
3. 画廊交互复用平台 pro.js 既有钩子（.pro-product-media /
.pro-gallery-thumbs / [data-gallery-image]）：缩略图点击换主图 + 主图灯箱，
零新增 JS；无 JS 时全部图片仍平铺可读。无图回退封面，再无则占位渐变
（空值不破版）。 #}
