+| 工作明细左侧长操作按钮 | Admin #621 真实 1920×1080 截图 `baiyue-firstleg/reports/appointment-browser-20261015/admin-621-follow-today-1920.png`；按钮与文本实际行高仅 13px | 保留完整文案和 108px 操作列，统一使用 20px 行高、自然换行和自适应高度；普通/展开面板及主操作/查看详情使用同一规则 |
 | 流程与工具栏分组 | 用户后续流程下拉、日期工具栏及上下操作区截图（`115df974`、`d217350b`、`80dd9fa1`） | 流程改为四个直接切换按钮；全局待办、流程、日期与类型筛选收进连续白底工作区，各行靠左，保留全局与区间统计边界 |
 | 日历浏览与日期选择 | 主页面截图；原型 `renderCalendar()`、`.day.selected`、`.todaymark` | 缩小日格空白，今天与选择态分别标识；零项日期只显示日期；显示实际查询起止日期，保留加载失败状态 |
 | 日期/类型/全局明细 | 展开截图中日历被挤窄；原型第 11 行 `.workspace`、`.panel` 为右侧覆盖布局 | 恢复覆盖式侧边工作面板，不压缩日历；增加展开/收起，标题和关闭固定，正文滚动，分页固定；仍保留左侧业务操作 |
