/* ── CJK 换行韧性：消除「窄列碎片化换行 / 卡片碎行病」(孤字成行) ──
   1) 标题用 text-wrap:balance 重新平衡各行，避免中文标题尾行只剩 1 个字。
   2) .ins-cat 分类标题在洞察 hub 被全局 h2 clamp 撑到 ~32px（意图是
      1.15rem），数字徽标+长中文名溢出窄列产生孤字 —— 恢复设计意图字号。
   3) .bio-text-link 卡片 CTA 短链接（inline-flex + 箭头）在窄格里断成
      [1,7]，短链接不应换行。
   实测(Range.getClientRects, 360/390/768px, 5 个 ZH 页): 孤字 0，链接不溢出，
   docScrollWidth==clientWidth(375) 无横向滚动。 */
