/* ---------- 本场景用到的工具 ----------
   注意：一律用 minmax(0, 1fr) 而不是 1fr。
   1fr 等价于 minmax(auto, 1fr)，其中 auto 的下限是「内容的 min-content 宽度」；
   而卡片里的 .tm-name / .tm-desc 是 nowrap + ellipsis，min-content 就是整行文字宽度
   （overflow:hidden 不会降低 min-content）。两者叠加会把三列撑到 1300px 以上，
   塞进 1080px 的容器后，第三列直接被 .scene-host 的 overflow-x:hidden 裁掉。
   这个坑只在 >1200px 三列时出现，≤1200px 媒体查询切成两列正好躲过。
   同一规律适用于下面所有网格。 */
