/* ===== 横向溢出修复 2026-09-21 =====
   1) .search-bar 的 flex:1 缺 min-width:0，最小内容宽被 input 默认宽度(142px)钉住，
      又因 flex-basis:0 无法收缩 → header 400px，全站横向溢出 40px；已在原处补 min-width:0。
   2) .topic-card{width:260px} 来自首页横向滚动卡，被多份样式拼接泄漏到专题合集页的
      .topic-grid{1fr 1fr}，1fr 的 auto 最小值=min-content=260px → 两列 530px 溢出 182px。
      仅在网格上下文恢复自适应，不影响首页 .hscroll 内的横向卡片。 */
