/* ==========================================================================
   语言切换：地球图标在 24×24 槽位里的视觉居中修正（全断点生效，不放在 @media 内）
   现象：图标看起来比右边的语言文字高约 1px，图标与文字没有水平对齐。
   成因：.lang 是 flex + align-items:center，槽位（24×24 的盒子）本身已经和文字
        行盒垂直居中了 —— 问题出在 lang.png / lang-black.png 这张 52×52 的图里，
        地球图形在画布中偏上（上方留白比下方少），background-size:contain 又让图
        正好铺满整个槽位，所以 background-position 调不动它，只能整块下移。
        实测（1x 截图，14px 文字）：图标墨迹重心 19.71，文字墨迹重心 20.43，差 0.72px。
   做法：整数下移 1px，保证图标在 1x 屏上不产生半像素模糊。
        换了新的、图形本身居中的图标资源后，请删掉这条规则。

/* 【839px 及以下不区分首页/子页，一律白底 + 红 logo】
   这里原先有一个 @media (max-width: 839px) 的 .not-home 块，
   给带头图的子页（body[data-header-transparent="true"]）强制透明底 + 白 logo + 白汉堡。
   已按需求删除：窄屏统一走首页那套响应式，data-header-transparent 在 ≤839 不再产生任何视觉差异。

   删掉就够了，不用另外补规则 —— ≤839 的白底状态本来就是全的：
   - 背景：768-839 / 600-767 / 480-599 / 360-479(含 ≤359) 四个断点里 .header 的基础 background 就是 #fff
   - logo：上面 @media (max-width: 839px) 里 .header .logo img 已是 logo-color.png !important
   - 汉堡：各断点 .header .nav-toggle span 已是 #222（滚动后 #333）
   - 语言：各断点 .header .lang 已是 #333，.globe 已是 lang-black.png（下拉箭头已按 UI 稿删除）
   透明头部现在只在 ≥840 生效，靠各断点 .header 的基础深色渐变实现，滚动后由 .header.scroll-active 转白。
   .not-home 这个 class JS 里仍在打，但 ≤839 已无 CSS 引用；若哪天要恢复窄屏透明头，
   记得同时处理 background / logo / 汉堡 / 语言四组，且务必带 :not(.scroll-active)：
   .not-home 那几条都带 !important，而各断点 .header.scroll-active 的白底规则没带，
   !important 会无视优先级照样赢，只删 .scroll-active 选择器是不够的。 */

   语言切换下拉框：对齐设计稿「组件 19」（2026-08-27）
   整块可以直接删掉，删掉就完全回到原样；上面 9 个手绘断点里的
   .lang-menu / .lang 一行都没动，这里全部用 !important 后置覆盖。

   按你的两个决定来的：
     1) ˅ 箭头加回来，展开时翻转 180° 变 ˄；
     2) 所有断点用同一套数值（原来 ≥1280 是 140/8/14px 一档、
        ≤1279 是 120/6/12px 另一档，现在统一成下面这套）。

   数值是从设计稿截图量的，按「文字 14px」标定出缩放比 1.57× 反推：
     面板宽 209/1.57≈132  圆角 22/1.57≈14  行高 80/1.57≈52
     左内边距 36/1.57≈23→24  小三角 34×14 → 22×9
     面板顶到 .lang 底 32/1.57≈20（原来是 12，三角占掉 9 之后正好接上）
   文字色量出来是 #222（原来写的 #333），当前项的红色量出来就是 --primary。
   设计稿面板外面几乎看不出投影，和现有的 0 12px 32px rgba(0,12,41,.12)
   量级一致，所以投影没改。

   ≤479 那档 .lang-switch 本来就是 display:none，这里没碰它，依旧不显示。

   mega 下拉面板：投影往上漏进 header，在白底 header 的下沿糊出一条灰渐变
   （2026-08-27）。整块可以直接删掉。

   成因：.mega-menu 是 .header 的后代（li.has-mega 是 position:static，
   所以定位参照的是 fixed 的 .header），子元素的 box-shadow 会画在父元素
   背景**之上**。它的投影是 0 8px 24px rgba(41,0,5,.05)：阴影矩形从面板顶
   下移 8px，Chrome 的模糊 σ = 24/2 = 12px，高斯尾巴能往上够到面板顶上方
   二十几 px —— 正好落在 header 的下沿里，所以一展开就多一层灰。

   量了用户那张图对得上：面板顶正上方那一像素，alpha = 0.05 × Φ(-8/12)
   = 0.0126，叠在白底上 = 255 - 0.0126 × (255-41) ≈ 252.3，
   截图量出来就是 252，再往上逐级 253 / 254 / 255 淡出。

   修法：给面板自己加 clip-path，上边沿切平（inset 的第一个值 0），
   另外三边放出 64px 让向下的投影照常显示。clip-path 会连 box-shadow 一起
   裁，所以往上那一截直接没了，向下的投影一点没变。
   面板本来就有 overflow:hidden，内容不会超出，不会多裁掉任何东西。

   只在 ≥1025 生效：≤1024 是侧滑抽屉那套，那边已经写了 box-shadow:none，
   本来就不漏。
