/**
 * 主题 tokens —— 设计变量的**单一事实来源**（JS 形态）。
 *
 * 颜色 / 间距 / 圆角 / 字号 / 阴影集中于此。`theme.css` 的 `--drama-*` CSS 变量与本对象一一对齐
 * （CSS 形态供组件 `<style>` 引用，JS 形态供调用方在脚本中读取 token 值）。新增品牌主题 = 在
 * `theme.css` 增一组 `[data-theme="..."]` 变量并在 `color.dark` 处补对应 JS 值，组件零改动。
 *
 * 设计语言对齐 `docs/design`：黑白主色、圆角 12–16px、标题 Space Grotesk / 正文 Inter。
