   本文件原是一套浅色排版：白底 #fcfdff、白卡片、深色文字，强调色 --catalog-blue
   为纯黑。这里统一翻成深色版：
   - 三个变量只在 .products-page-main 作用域内重定义，其它页面不受影响；
     --catalog-blue 由纯黑改为品牌橙，作为深色底上的强调色
     （标题高亮字、选中的分类、搜索按钮、当前页码等都自动跟着变）
   - 其余写死的白底 / 浅色边框逐个覆盖
   覆盖规则放在文件末尾，因此对上面 max-width 媒体查询里的同名规则同样生效。

/* ==========================================================================
   产品中心页：背景图 02-2.jpg 铺在「全部产品」这一行，左右通栏不留黑边
   范围 = .catalog-layout 所在这一行（左侧分类栏 + 右侧全部产品），
   不含顶部「产品中心」横幅 —— 横幅保留它自己那张压暗的矿山图与深色渐变。

   原来的 .catalog-layout 是 min(1440px, 100%-80px) 居中，左右会各留 40px 黑边。
   这里把容器本身改成铺满整行（width:auto + margin 0），再用左右内边距把内容
   推回原来的位置：
     padding-inline = max(40px, (容器宽 - 1440px) / 2)
   这样内容宽度、位置与原来完全一致，背景却能一直铺到屏幕两侧。

   黑色蒙版用 85%，与首页「产品中心」模块一致：图片只作底纹、若隐若现，
   整个区块仍读作深色，白字与深色卡片都能压得住。
