 *   --c-on:#18a058         启用/成功(绿)
 *   --c-off:#9aa1b3        停用(灰)
 * 字体：base 14px；辅助 12-13px；标题 16-20px
 * 间距：区块间距 20-22px；单元格 padding 8-14px
 * 圆角：卡片 12px；按钮/标签 6-8px；胶囊 20px
 * ------------------------------------------------------------
 * 表格布局规范（强制）：
 *   - 用 .tbl-compact（固定紧凑 padding）或 .tbl
 *   - 短文字列（状态/模式/标签）必须 white-space:nowrap，禁止折行
 *   - 列宽均匀，不留大片空白；数字列 text-align:center
 *   - 多分辨率(375/768/1280)截图核对无溢出
