/* Material 3（含 Expressive 形状指引）

 * 形状层级刻意分级，遵循两条规则：
 *   - 重要动作不能给小圆角（Smaller shapes can result in essential actions looking less important）
 *   - 用形状打破节奏来突出某个元素（Break from the surrounding shape style）
 *
 *   36   hero            最大容器，锚定页面
 *   28   卡片 / 面板      常规容器
 *   24   统计块 / 主按钮   主按钮故意用大圆角矩形，与药丸形次级按钮形成对比
 *   20   代码块 / toast
 *   16   输入框
 *   999  次级按钮 / chip  低权重
 *
 * 颜色 token 由 ui/theme.ts 运行时按种子色生成。
