/* ============================================================
   柒柒资源社区 SourceVault · 前台 / 后台样式（简约版）
   ------------------------------------------------------------
   设计原则：
     · 大留白、细描边、单一主色点缀、大字号标题
     · 不堆装饰层：没有渐变光晕、没有玻璃拟态、没有阴影森林
     · 卡片一律 1px 细边 + 12px 圆角，hover 只做轻微位移和描边加深
   主色由后台「站点设置 → 主色」注入到 --brand。
