/* ==========================================================================
   科技蓝大气版皮肤 —— 只覆写设计令牌与本套首页新增的结构
   加载顺序在 css/site.css 之后；页头、导航、栏目页、详情、搜索、页脚全部复用标准版，
   换肤不复制一份全站样式，避免两套 CSS 长期分叉。
   内页不随本套皮肤改动版式：这里新增的选择器都以首页专有结构（kdark/khero/kpower/kcards
   /kstats）或首页才会出现的元素为前缀，避免误伤内页。
   配色口径：#0066ff 只做提亮（按钮、序号、链接、悬停），深色段一律由 --kdeep-1 → --kdeep-2
   → --brand 的渐变打底，渐变末端推到画框外（120%），避免大面积纯亮蓝显得喧哗。
   深色区里的分隔线统一走 --kline，正文走 --ktext / --kmuted，不各自写死白字透明度。
