/* ============================================================
   冬天快乐 · 雪后清晨  浅色冬季皮肤（v2 全模块适配版）
   ------------------------------------------------------------
   作用域：html[data-season="winter-light"]
   目标：整站由「深紫夜」翻成「雪白昼」，且每个模块都要看清

   设计规则（v2 新增）：
   1) 底色整体压深一级 → 白卡片才能"浮起来"，模块边界清楚
   2) 表面三层：page(#eef7ff→#cfe1f2) / card(#fff) / inset(#f1f7fd)
   3) 正文一律 ≥ 7:1，次要文字 ≥ 4.5:1，强调色一律压深
   4) 所有「浅金 / 浅橙 / #fff」硬编码文字，逐模块重映射为深琥珀
   5) 保留深色：图片灯箱、打卡裁图工具（本就是深色工具面板）
