/* ============================================================
   体测管理系统 · 响应式样式
   风格：浅色底 + 蓝色渐变主卡 + 白色圆角卡片 + 药丸标签
   断点：xs<480 / sm 480-767（手机）· md 768-991（平板）· lg>=992（电脑）· xl>=1440（宽屏）

   ⚠ 两条"防挤压"铁律（改样式前先看一眼）：
   1. .btn 永远 white-space:nowrap + flex:0 0 auto —— 否则在 flex 行里会被压成竖条（"查询"两个字上下叠）
   2. 窄屏下 .row.nowrap 必须允许换行，输入类控件给 min-width:0 —— 否则下拉框被裁成"全部班"

/* ---------------- 手机端横向溢出兜底（2026-10-14） ----------------
   背景：用户报告在校园门户 App 里"下面内容超出手机宽度、不会自动调整"。
   本机在 320–430px、以及"文字放大 1.5 倍"下都复现不出来（逐元素扫描无越界），
   怀疑是 WebView 的文本缩放/布局宽度差异。这里做**兜底**：
   宁可把个别过宽的块裁掉，也绝不让整个页面横向跑出屏幕 —— 手机端不该出现横向滚动条。
   ⚠ 表格不受影响：它们都在 .tbl-wrap（自带 overflow-x:auto）里，仍旧可以左右滑动。
   ⚠ 只在手机端生效（≥768px 的桌面端不动，那边双栏布局依赖完整宽度）。 */
