/* HOVOD — mobile visual system
 * Reference implementation: dark cinematic UI, restrained teal accent,
 * 16:9 media surfaces, compact typography, bottom five-position navigation.
 *
 * 全屏自适应模型（2026-09-17 重写）
 * ------------------------------------------------------------------
 * 旧模型把**整站外壳**锁在 --shell(430px) 的居中列里：`#app{max-width:430px}`。
 * 后果（实测，见 scripts/verify-responsive.mjs）：
 *   - 1280×800 下 #app 只有 430px，两侧各空 425px；欢迎页背景图退化成一条竖条
 *   - 每屏都固定多出 28px（`.screen` 的 padding-bottom 叠在 100vh 之上）→ 落地页无故可滚
 *   - 视口高度用 vh（移动端"最大视口"），与浏览器 UI 收放后的可见高度不一致
 * 新模型分三层，各自承担一件事：
 *   ① 外壳 #app / .nav  →  满幅（width:100%，无 max-width）
 *   ② 视口高度          →  --app-h（dvh 优先，vh 兜底）
 *   ③ 内容可读列        →  --content（只在大屏生效，约束"内容"而非"外壳"）
 * 外加安全区（刘海 / 底部横条）由 --safe-top / --safe-bottom 统一承担。

/* ⚠️ 这一条必须存在，且必须放在 .nav 规则之前。
   UA 的 `[hidden]{display:none}` 与 `.nav{display:grid}` **特异性相同**，
   而作者样式优先于 UA 样式 —— 所以只写 `.nav{display:grid}` 会让 hidden 彻底失效。
   这不是理论问题：欢迎页（非 tab 屏）的 nav.hidden 一直是 true，
   但导航照常渲染，并把落地页的 CTA 与底部文案压在下面（实测 props 被遮 42px）。
