/* ==========================================================================
   2RTK NTRIP Caster — 亮色主题（与 2RTKserver / NTRIPserver 保持同一套设计语言）
   --------------------------------------------------------------------------
   设计约束：
   1) 不依赖任何 CSS 框架/CDN。布局、颜色、组件全部由本文件承载，断网时依然是
      一个完整页面（原实现依赖一张渐变背景 + 大量内联样式，升级后端时经常出现
      "样式新旧混在一起"）。
   2) 单一强调色（蓝 #2563eb）+ 中性灰阶做信息分层，语义色只用于状态。
   3) 保留少量科技感：品牌名用 Orbitron、卡片顶部一道蓝→青渐变细线；其余一律
      克制，不再用霓虹投影/发光边框。
   4) 本文件同时承载历史类名（.dashboard-card/.stat-item/.card-content 等），
      app.js 里已有的标记不需要大改即可套上新皮肤。
