+ * 后台全局 UI 统一规范 (2026-08-18 建立, 2026-08-21 补约定注释)
  * 由 UI 审查驱动, 解决跨页视觉一致性缺口:
  *   1. 页面骨架统一 (rr-page 默认内边距)
  *   2. 表格视觉统一 (表头底色/圆角/消除老页面 border 竖线)
  *   3. 卡片圆角统一
  *   4. 状态标签/el-tag 暗色主题适配
  * 设计原则: 只做"兜底默认", 页面 scoped 样式优先覆盖
+ *
+ * ────────── 组件使用约定 (审计后定) ──────────
+ * ◆ 状态呈现:
+ *   - 列表页表格的状态/标志列: 统一用 `.st-pill` (圆点+胶囊, --st-* token)
+ *     例: <span class="st-pill" :style="{color,background}"><span class="st-dot"/>正常</span>
+ *   - 详情页/向导/标签: 用原生 <el-tag type="success|warning|danger|info">
+ *     (global-ui.scss 已写 el-tag 四态暗色适配)
+ *   - 不要混用: 同一项目里两种风格并存会出现"有没有圆点"的视觉差
+ *
+ * ◆ 表格列对齐:
+ *   - 识别性内容 (名称/手机/编号/地址) 左对齐, header 也左对齐
+ *   - 纯数据 (时间/金额/数量/状态) 居中, header 也居中
+ *   - 操作列固定居中且 fixed="right"
+ *
+ * ◆ Dialog 宽度: 仅允许 4 档 — 500px(small) / 640px(medium) / 800px(large) / 960px(xlarge)
  * ============================================================ */
