/* ============================================================
 * v4-scene.css —— v4 实景界面（20260909 拍板稿落地）
 * ============================================================
 * 依据：design/v4-style/screens-v4.html（老板逐屏拍板通过）
 *   1. 竖版原生场景全幅铺底（7 张 AI 重绘原创图，refs/v4v → assets/scenes/v4）
 *   2. 牌匾系统：万象学宫（登录）/ 青云宗（宗门）/ 灵药铺·街市 / 铁匠铺·器殿 / 云溪客栈·宗门
 *   3. 主城减负：只留 HUD + 三店匾 + 木牌热区（心魔塔/石桥·论剑台/布告栏·仙榜）
 *   4. 九秘境：左右交错疏排胶囊（防误触，行距拉开）
 *   5. 动态：仙鹤扇翅 / 浮云漂移 / 金尘（prefers-reduced-motion 时自动关闭）
 * ============================================================ */
