   -----------------------------------------------------------------
   分层(从上到下):
     1) TOKENS    设计变量(color / space / text / radius / shadow / motion)
                  改主题色 / 调全局间距只动 :root
     2) BASE      reset / typography / generic 容器
     3) COMPONENTS 命名组件(.admin-panel / .btn / .tbl-toolbar / .pager 等)
     4) UTILITIES 单职责工具类(.u-mt-* / .u-text-* / .u-flex 等)
                  仅用来替代"inline style" 的微调,不要拼复杂布局
     5) RESPONSIVE 媒体查询断点(@media)
   -----------------------------------------------------------------
   命名约定:
     .foo-bar          BEM 风的组件类
     .foo--variant     组件变体
     .u-mt-3           utility(允许放在 HTML 里)
     style="..."       仅当值是模板动态(width:{{.Pct}}%)时允许
   颜色规则:
     ink/ink-2/ink-3   文字主/次/弱(三档够用,别加新档)
     paper/paper-2/3   背景主/次/卡(同上)
     signal            mint/cyan CTA / 当前激活态(全站唯一品牌强调色)
     ok/warn/danger    语义色 + -soft 软底 + -rim 边
   间距规则:
     space-1 .. 7 = 4 / 6 / 8 / 12 / 16 / 24 / 36 px
     padding / margin / gap 全部走这套,不要写 10px / 14px 这种"中间值"
   文字尺寸:
     text-xs(11) / sm(12) / base(13) / md(14) / lg(15) / xl(19) / 2xl(28)
