/* ============================================================
   机器人前线 — styles.css  v4 「晨光工业风」
   ------------------------------------------------------------
   v3 的问题：整站近黑底，压抑，科技感靠发光堆出来，久看疲劳。
   v4 的思路（参考宇树/智元官网的做法）：
     - 主体是**亮面**：近白偏冷的底 + 大留白 + 细线框
     - 深色只在两处出现：首屏 hero 和末尾订阅区 → 形成明暗节奏
     - 色调从单一青色扩到三色：靛蓝(主) / 青(辅) / 琥珀(强调) + 洋红点缀
     - 渲染感靠**大面积柔和渐变 + 网格 + 玻璃卡**，不靠 glow 描边
   所有可调项集中在 :root。不引外部字体/CDN。
