/* ============================================================================
   BoxKit — 视觉系统 v5 “现代产品站 / Product”
   零依赖、零外部请求（不引任何 webfont；图标一律内联 SVG）。

   设计语言（对标 iloveimg 这类成熟工具站，而不是杂志/海报）：
   · 底：浅灰紫 #f4f5fa，卡片纯白浮起来（靠阴影分层，不靠描边）
   · 字：无衬线。标题大而稳（42px/700），正文用柔和深灰 #5b6070，不用纯黑
   · 色：主色蓝 #2f6bff；每张卡片配一块**彩色圆角图标砖**，这是“像产品”的关键
   · 形：圆角 12–16px，阴影柔和，悬停微微抬起
   · 暗色：同一套排版，底换深蓝黑，色砖自动降饱和
