/* ---------- 文章卡片墙(2026-09-16 改版):最新一篇大图横排,其余三列小卡片 ----------

   小卡片只留图、日期、标题;先露置顶 + 一排,其余由 js/site.js 收起来、点 Show all 展开(同 Events 页「所有场次」)。
   卡片由 tools/sync.js 生成:posts 第一条用 partials/post-feature.html,其余用 post-card.html。
   2026-09-16 加了搜索和「小卡片点开看摘要」:摘要 + Read more 收在 .news-card__detail 里,js/site.js 接管后才收起来;
   搜索时置顶大卡退场,换成它的小卡片版(.news-card--mirror,平时藏着),结果一律是小卡片。 */
