/* 视觉方向：双面工作台（Split Console）。
 * 深石墨顶栏与侧栏是"设备壳"，暖纸色消息区是"工作面"：外壳负责状态与导航，
 * 纸面负责阅读。识别色只有一枚信号黄绿，且只压在深色底上；纸面上的主按钮
 * 反过来用墨色底 + 信号色文字，保证浅色底上的对比度。
 *
 * 三条约束：
 * 1) 只用系统字体与本地资源，不引外链字体/CDN（docs/mvp.md §2.7）。
 * 2) 不改动 app.js / ops.js / memory.js / skills.js / voice.js 依赖的 id 与
 *    class 契约；本文件只负责这些既有节点的外观。
 * 3) 390px 窄屏、键盘焦点、prefers-reduced-motion 必须可用。
