/* =====================================================================
   OpenClaw Design System v2 (Sample D · A 密度 + C 色彩)
   ---------------------------------------------------------------------
   - 兼容旧 token 名（--bg-primary / --bg-card / --text-primary ...），
     旧组件无需逐个改样式即可继承新视觉。
   - 新增 token 别名（--surface / --fg / --muted / --accent-soft ...），
     供新组件（.check / .switch / .multiselect / .tbl ...）使用。
   - 默认跟随系统 prefers-color-scheme，用户手动切换写入 localStorage。
