/* ============================================================================
   慵懒半径 v2 · core.css（核心通用样式合并）
   ----------------------------------------------------------------------------
   合并自旧版：base / buttons / loading / toast / header / fab / image-viewer
   改造点：
     1. 删 32s 浮动光斑动画 → 静态 mesh gradient（决策17，省 CPU）
     2. 紫色阴影残留（rgba(79,70,229)）→ 珊瑚橙（rgba(249,115,22)）
     3. 桌面断点 900/1400 → 768/1024/1440 四档（决策16）
     4. 全部用新 token（--brand/--slate-*/--elev-*/--r-*/--sp-*/--fs-*）
  /*   5. 删 glass.css !important 覆盖层（新 token 干净，无需补丁）
     6. 保留双环旋转 loading（珊瑚橙+天蓝，用户偏好）
     7. 全局 loading 无文字右侧点动画（约束）
