   3D 立体服装图（图片板块 · 子页 sub-to3d）· 样式
   —— 类名前缀 td-（已跑 check-css-collisions.py 确认全局唯一）
   ----------------------------------------------------------------------------
   配色说明：图标品红紫 H=306°（#d50bc1 → #5c0a55）。
   它是用 **CIE Lab 感知距离**在图片板块已占色相里算出的最大空位，不是肉眼挑的。
   白字在浅端对比度 4.52:1，达 WCAG AA。
   ⚠️ 2026-09-23 本功能由「2D转3D」整体替换为「3D立体服装图」，
      技术标识（sub-to3d / 路由 / 类名前缀）**故意保持不变**（见 lib/tod3.js 头注），
      只把布局从"上传→强度→视频结果"改成"上传→立体程度→背景画幅→成品图"。
