/* =============================================================================
   cc-structure.css — 纯结构层（不写颜色，主题由 cc-skin 决定）
   cnext design system · 个人 mark: cc

   设计原则：
   - 只用 display / position / flex / grid / padding / margin / width / height
   - 颜色全部走 token（var(--xxx)），不写死任何 hex / rgba 颜色
   - box-shadow 颜色部分走 var(--shadow*) token
   - 形状/动画/transform 随便写

   引入顺序：cc-reset.css → cc-tokens.css → cc-structure.css → cc-skin-*.css
