 *     --surface / --accent / --danger / --radius 等同名变量冲突，
 *     保证未迁移页面零影响。
 *  2. 仅声明与现有应用不冲突的基础组件类（.btn-quiet / .status-pill /
 *     .due / .icon-btn / .input / .section-label / .empty-block / .sk-row /
 *     .main-tag / .tt-block）与全部 .biz-* 业务类。
 *     .card / .checkbox / .error-banner / .btn-secondary 已存在于应用，
 *     待对应模板迁移时再在组件层就地收敛，不在此全局覆盖。
 *
 * 通过 dashboard.css 的 @layer(design-system) 作为最高优先级层引入。
 * 模板逐个改用 .biz-* 后即可生效；未改的模板继续走 legacy 层，互不干扰。
