/* [BRAND_NAME]前端手机端响应式覆盖 v9
 *
 * 背景：frontend/ 是从 [SITE_DOMAIN] 抓的冻结 minified bundle，
 *      上游基本没做移动端适配（grep @media 仅 1 处、mobile/phone 关键字 0 次），
 *      desktop 三栏布局硬塞进 390px viewport 时：
 *        - 侧栏被等比挤压成 146px（模型列表一指宽不可读）
 *        - 主区 .sora2-main-content 只剩 243px
 *        - .scroll-content / .right-section 仍按 desktop 宽度（500-600px）渲染溢出
 *
 * 修复路径：注入本 CSS + heizhu-mobile.js，在 ≤768px 时强制：
 *   1. 侧栏（含 .sidebar-logo / .model-list / .user-section-content 的父容器）→ fixed 抽屉
 *   2. 主区 .sora2-main-content → 全宽，给 hamburger 让顶部 56px
 *   3. .scroll-content / .right-section → 100% 宽，wrap
 *   4. body 加 .heizhu-sidebar-open 时抽屉滑出
 *
 * 侧栏父容器 class 用 JS 打（.heizhu-mobile-sidebar），避免依赖 :has() 兼容性。

  /* 底部输入框区（聊天/图片生成页）。

   * 两个 desktop 设计在 mobile 都需要覆盖：
   *   a) 原本是 `position: absolute; left: 50%; transform: translateX(-50%); width: 530px`
   *      做经典居中。mobile 改 100% 宽后 translateX(-50%) 会把整块推到 x=-195。
   *   b) wrapper 是 absolute 相对 .sora2-main-content（高 100vh）定位。iOS Safari 键盘
   *      弹出时会自动 scroll 整页让 focused input 可见，wrapper 跟着主区一起被向上推
   *      到屏幕中央——用户感知就是「输入框被顶走了」。
   *
   * 修复策略：
   *   - 改 position: fixed 脱离主区滚动上下文，bottom: 0 贴 viewport 底
   *   - 用 visualViewport API 算键盘高度写入 --heizhu-kb-inset CSS 变量，
   *     translateY(-inset) 让 wrapper 始终贴键盘顶（详见 heizhu-mobile.js）
   *   - 键盘没弹时 inset=0，translateY(0) 等价于 transform: none（也顺便清掉
   *     上游 inline 的 translateX(-50%)）
   *   - padding-bottom 用 safe-area-inset 兜底 iPhone 底部安全区
