   ★ v39.30：课程表「一屏放下」真修复（微信 / 手机窄屏）
   ------------------------------------------------------------
   ⚠️ 上一版 v39.29 改的是 .tt-table / .tt-cell / .tt-slot —— 那是历史遗留的
      「网格版式」死代码，全站 JS/HTML 都不再生成 tt-* 类名。
      dashboard.js 真正渲染的是普通表格：
          <table class="schedule-table">  (st-period / st-cell / st-subject / st-meta)
      ⇒ v39.29 的 CSS 从未命中，周四、周五依旧被裁到屏幕外。

   真根因（数学上必然溢出）：
      .st-cell   { min-width: 88px }        ← 每列最小 88px
      .st-period { width: 72px }
      ⇒ 表格最小内容宽 = 72 + 5×88 + 边框 ≈ 512px
      ⇒ 而手机可用宽只有 ~330px；外层 .schedule-grid-wrap 又是 overflow-x:auto
      ⇒ 周四/周五被推到屏幕右侧之外，微信里几乎拖不动，用户以为"没有课"。

   修法：table-layout:fixed + width:100% ⇒ 列宽由表格宽度均分，不再看内容脸色；
        再把 .st-cell 的 min-width 归零、文字允许换行 ⇒ 数学上不可能溢出。
