/* ============================================================================
   觅智社区 · 首页内嵌样式（forum.css 的 namespace 子集）
   - 所有规则以 .community-section 为前缀，不污染其他页面
   - 复用 index.css 的 :root CSS 变量（与 forum.css 同色系，已对齐到 #4a5ce0 靛紫）
   - 不复制全局 reset（html/body/main 等），由 index.css 负责
   - 子类名（post-card / tag / meta / card-link ...）是 forum.js buildCard() 写死的，
     必须同名；通过父级 .community-section 隔离作用域即可
   - 例外：.cpm-* 为帖子详情弹窗样式，弹窗由 JS 懒挂载到 <body>（.community-section
     之外），故不加前缀；配套 body.cpm-open 滚动锁
