/* 提瓦特答题祭 —— 明亮配色 + 液态玻璃。
 *
 * 设计思路（写给以后接手的人）：
 *   ① 底色不做纯白，做"清晨的提瓦特"：天空蓝 → 薄荷绿 → 淡金 的多层径向渐变，
 *      再叠一层极淡的噪点，玻璃才有东西可以折射，不然白糊糊一片；
 *   ② 玻璃卡片 = 半透明白 + backdrop-filter(blur+saturate) + 1px 高光边
 *      + 顶部镜面高光(::before) + 噪点(::after)，这四样缺一样就"塑料感"；
 *   ③ 七元素色只用在**点缀**（标签、进度、排名徽章、按钮描边），不要大面积铺；
 *   ④ 装饰全部是 CSS/SVG 画的：风车、元素晶球、羽毛、星屑 —— 不依赖外部图片，
 *      加载快、不会挂、也不涉及素材版权。
