/* ==========================================================================
   迈邦科技 · 明亮 AI 现代风（v2.3.0）
   --------------------------------------------------------------------------
   设计取向：白 / 浅灰底 + 柔和彩色光晕（极光感）+ 大圆角玻璃白卡 +
             细发丝线 + 大字重渐变大标题，通透干净。
             科技感来自光影与渐变，而不是靠深色底。
             桌面宽屏舒展，手机 / 平板完整单列自适应。

   兼容要求（不要删）：
     1) 仍保留 CSS 变量 --blue / --gray，因为数据库里旧页面正文有内联
        style="color:var(--blue)" / style="color:var(--gray)" 的引用；
     2) 仍覆盖旧页面正文用到的全部类名：.hero .product-hero .feat-grid
        .ss-grid .flow .tool-list .about-grid .sites .contact-grid
        .dl-card .changelog 等；
     3) 抽屉导航断点必须为 1000px，与 assets/js/main.js 的
        matchMedia('(min-width:1001px)') 对齐。
