/* ============================================================
 *  户型 3D 互动 · 工作台样式（floorplan.css）
 * ------------------------------------------------------------
 *  上游：floorplan-3d（MIT，https://github.com/wy51ai/floorplan-3d）的 <style> 段，
 *        原样迁移，**只做一件事：把所有选择器收进 #fpApp 作用域**，
 *        避免与 site.css 的通用类名（.btn / header / main / footer / .item…）互相污染。
 *
 *  与上游的差异（就这三处）：
 *    1  选择器统一加 #fpApp 前缀；html / body / :root 映射为 #fpApp 本身
 *        —— 上游把 html,body 写成 height:100% + overflow:hidden，会**锁死整站滚动**
 *    2  .app 的高度由 100vh 改成 100%（高度交给外层 #fpApp 决定）
 *    3  文件尾部「本站新增」一段是本站在官网上用的容器与首屏海报样式
 *
 *  ⚠️ 上游段落尽量别手改，方便日后同步上游；视觉调整优先改 CSS 变量与「本站新增」段。
