/* ==========================================================================
   TEAM JBYangC — 全站样式表 / Global stylesheet
   --------------------------------------------------------------------------
   设计原则 / Design principles
     1. 简约：大量留白、克制的描边、只用一条强调色渐变贯穿全站
     2. 平滑渐变：所有过渡统一使用长缓动曲线，动效不抢内容
     3. 专业正式：排版以信息层级为先，装饰元素一律降饱和度
     4. 保留娱乐内核：文案区留出呼吸感，卡片交互带一点轻快的上浮
   ========================================================================== */

/* ==========================================================================
   1. 设计变量 / Design tokens
   --------------------------------------------------------------------------
   默认深色。浅色在同文件下半部分的 [data-theme="light"] 里覆盖同一组变量，
   其余规则一律通过变量取值，所以切换主题不需要重写任何组件样式。
