+/// 轻量分段选择器（UI06 对齐 app-preview .tabs）。
+///
+/// 形态：#EDF1F6 轨道、padding 4、整体圆角 9；选中实底、未选次文字色。
+/// 两种选中风格：
+/// - [SegmentTabsStyle.solid]：主蓝实底白字（上传中心筛选等状态筛选）；
+/// - [SegmentTabsStyle.light]：#DBEAFF 底 + #145BB9 字（Details/Access 类
+///   内容页签——与状态筛选区分，见 app-preview .tabs.light）。
+///
+/// 替换默认 [SegmentedButton]（M3 黑边胶囊形态与示例不符）。
