/* ==========================================================================
   应用方案页专用样式（批次二十三）
   --------------------------------------------------------------------------
   作用域：所有规则以 .app-page 开头，只在本页生效，不污染 style.css。
   涉及页面：/applications.html（列表）、/application/{slug}.html（详情）

   设计约束：
   1. 中文正文 17px / 行高 1.85，行宽控制在 50 字左右（中文最佳 40-50 字）；
   2. h2 与上文之间必须有 54px 呼吸，原来 margin 是 0，这是整页显乱的主因；
   3. 卡片一律 flex 等高，图片回到文档流，不再用 absolute 定位；
   4. 5 个品类用 flex 居中网格，最后一行 2 个自动居中，不留右侧空格。
