/**
 * UI copy (bilingual): this file holds the Chinese dictionary `zh` and the runtime
 * active dictionary `S`; the English dictionary lives in strings-en.ts (constrained
 * to the same shape by the `Strings` type). Locale preference is resolved by
 * state/locale.tsx, which calls `setActiveStrings` to switch and remounts the whole
 * tree keyed by locale, so `S.x` reads in components always reflect the current
 * language (module-level constants do not update on switch — keep reads inside components).
 * Keep domain terms capitalized in English — Workspace, Token, Task, Session, Project, Trace.
 * "agent" is a common noun: lowercase mid-sentence, capitalized only at the start of a
 * label/sentence or in a proper name (Agent State, AgentHub). zh keeps "Agent" as-is.

## 技术约束
- 使用 SC.Widget JS API（widget.load / widget.toggle / widget.setVolume / widget.seekTo），引入 https://w.soundcloud.com/player/api.js
- iframe 必须可见（180px 高），visual=true color=f0b90b single_active=true
- 仅包含以下 8 首已确认可播曲目（oEmbed 验证通过），不要添加未经 oEmbed 验证的曲目：
  - Warriors (S4) — soundcloud.com/leagueoflegends/warriors
  - Worlds Collide (S5) — soundcloud.com/leagueoflegends/worlds-collide
  - Legends Never Die (S7) — soundcloud.com/leagueoflegends/legends-never-die
  - Phoenix (S9) — soundcloud.com/leagueoflegends/phoenix
  - Burn It All Down (S11) — soundcloud.com/leagueoflegends/burn-it-all-down
  - GODS (S13) — soundcloud.com/leagueoflegends/gods
  - Heavy Is The Crown (S14) — soundcloud.com/linkinpark/heavy-is-the-crown
  - Sacrifice (S15) — soundcloud.com/leagueoflegends/sacrifice

## 布局
- 左侧 260px 粘性侧边栏：曲目列表（S4/S5/… 标签 + emoji + 曲名 + 年份），点击高亮金色边框，SC.Widget.load() 切歌 + auto_play
- 右侧主区域：Hero 标题 + 桌面时钟（80px 等宽金色 HH:MM:SS，每秒刷新，冒号闪烁）+ 心情标签
- 播放器卡片：SoundCloud iframe + 自定义控制栏（⏮ ▶/⏸ ⏭ + 曲目信息 + 音量滑块，点击喇叭图标静音切换）
- 心情波动区：15 根金色动画柱，切歌时重新随机生成
- 键盘快捷键：空格播放暂停、← → 切歌、↑ ↓ 调音量

## 设计
Penguin 视觉风格（见 web-design 技能），深色/浅色主题（<html data-theme>），默认深色，localStorage 记忆。响应式：手机端侧边栏变为顶部横向滚动。
