/**
 * product-hero block styles — 1:1 移植 bale-opener 原型的 `.product-hero`
 * （数值取自原型渲染后的计算值，原型 CSS 有 7 层覆盖，前面的规则基本是死代码）。
 *
 * 与原型的差异只有两处，都是刻意的：
 *   1. 原型 final.css 把按钮 / 播放钮全局改成 ZHOUJI 红 #ed1c24，那属于「全局」
 *      品牌层（同一段还改了页头页脚），本次只做产品内容，因此仍用站点橙 #e86e1b。
 *   2. 轮播动效重写（原型是硬换 img.src，没有任何过渡）——见 assets/product-hero 段。
