/* ══════════════ 移动端排版修正（2026-09-14，全站收口） ══════════════
   症状一：26~36px 的标题配 2~4px 字距，在 390px 屏里 11 个字就折行。
           改法：字号/字距随视口线性收缩（390px→19.1px，320px→15.7px），
                 ≤16 字的标题稳定排成一行；真正长标题才允许折行。
   症状二：部分 640px 的「单列」规则被文件后半段的 980px 规则按源码顺序反超，
           手机上仍按 2~4 列排，文字被压成一字一行的竖排。
           改法：所有单列规则在文件最末重新钉死一次，源码顺序再也反超不了。
   ⚠️ 本块必须留在文件末尾。 */
