/* ==========================================================================
   小星火 xiaostarfire.cn · 视觉质感升级 v2（2026-09-13）
   --------------------------------------------------------------------------
   设计方向（对标 api.careertick.com 的克制与留白）：
   - 顶栏由高饱和紫色渐变改为「浅色磨砂玻璃」，紫色只保留给品牌字标与选中态
   - 字体分层：品牌内容用 LXGW 文楷；导航/按钮/标签/数字等 UI 层改用系统无衬线，
     让界面「更锐利」，正文保持温润
   - 统一圆角（16/20/999）、极轻阴影（1px~2px 底影 + 大范围柔影）、克制的强调色
   - 眉题（eyebrow）替代粗重的章节下划线；卡片悬停做位移 + 阴影 + 图片微缩放
   - 表单/分页/页脚等基础件一并收敛，减少「Bootstrap 默认脸」
   加载顺序在 xiaoxinghuo.css 之后，仅做覆盖，不改动既有模板的类名契约。
