 * 窄屏（<=900px）首屏主列横向撑满（2026-10-29）
 * MARKER: cols-stretch-narrow-20261029
 * 实测：390×844 手机首页主列 #pt-main-content 只有 239px，右侧空 131px，
 * 观感就是「右边留白太多、和左边不对称」。
 * 原因：.pt-cols 自带 align-items:flex-start（style.css:260）。窄屏时它被改成
 * flex-direction:column，此时交叉轴是「横向」，flex-start 让子列不再拉伸、
 * 退化成 fit-content；而兄弟 .pt-side-col 另有 width:100%!important 是满的，
 * 于是两列不对称、右边空一大块。
 * 改：窄屏下 cross-axis 恢复 stretch，并给子列兜一个 width:100%/min-width:0。
 * PC（>900px）仍是 row + flex-start（侧栏顶部对齐），不受影响。
