/* ============================================================
   Light 模式灰字提对比（v1）
   用户反馈：白色模式下文字若是灰色，可读性太差。
   根因：v6 把 light 大背景从浅天蓝改为冷雾灰蓝(#b8c4d8/#95a5c2)，
   原来在浅亮底上的那批中浅灰字(meta/计数/分类/引用/侧栏小字/链接)
   在冷雾底上对比度严重不足(WCAG 普遍 <4.5:1)。本文件把这些灰字
   整体加深到深中灰/深蓝灰，并加强主题链接色，dark 模式全部不动
   (dark 底色本来就深，原色对比度足够)。
