 * public/spinvid.css —— 商品旋转视频（2026-09-19 · 开发员15号）
 *
 * 🔴 三条纪律（写这个文件之前必须知道）：
 *   ① **类名一律 `spv-` 前缀**（已核：全站 CSS/JS/HTML 里 `spv-` 完全没被占用）。
 *      别用裸类名 —— 「老板记账」的 `.lg-*` 就是被「法务顾问」的 `.lg-*` 覆盖过，
 *      按钮变成白底白字，零报错、只有用户点得到才发现。
 *   ② **本文件必须排在 style.css 之后加载**，否则会被通用规则盖住。
 *   ③ **不引入新色相**：整页只有一条色轴 ——
 *      深紫黑（#17131f→#0c0912）+ 洋红强调（#e879f9 / #86198f，色相约 294°）。
 *      294° 是视频板块色相环上最大的空位（已占 0/21/38/142/164/189/217/243/258/330，
 *      离最近占用色 36°）→ 跑 `node tools/audit-icon-colors.cjs --view video` 可复验。
 *
 * 视觉意图：**"展台"**。深色底把商品衬出来，这是电商高级感的通用语法 ——
 * 明度对比拉开，商品才是主角，界面本身要退到后面去。
