/* ==========================================================================
   昆仑智创 · 官网样式 v6（深蓝有光 / Bounded Sections）
   设计意图：一屏说清"做什么、怎么干、多久见效"，但底色要能看见蓝。
   - 深蓝底：从 #0a1a33 到 #123a63 的三层蓝，带青色与金色光晕，不用近黑
   - 每个板块都有可见边界：独立底、四周描边、顶部一条发光基线
   - 板块内部不再"浮在背景上没边"，一律落在 .plate 玻璃面板里
   - 白字 + 金→浅金渐变强调，品牌蓝金不变
   ========================================================================== */
