/* ai-home.css —— 产品内首页（AI 解读版）专用
 *
 * 作用域：全部选择器以 .ai-home 开头，不影响欢迎页 / 录入页 / 其他结果页。
 * 加载顺序：必须排在 home.css 之后（旧的 hm- 样式仍被 loading/error 态使用）。
 *
 * 与原稿的三处差异（都是为了不跟现有体系打架）：
 *  ① 颜色直接用项目 :root 的 --bg/--gold/--gold-bright/--text，
 *     不再自建一套 --ai-home-* 硬编码色值 —— 否则以后改主题要改两处。
 *  ② 不设自己的 width/margin-inline。外层 .app(max-width) + .views(padding)
 *     已经限定了宽度，再加一层会让首页比其他 tab 页窄一圈、左右对不齐。
 *  ③ 卡片正文不用 min-height 撑等高，改由 grid 拉伸 + 链接 margin-top:auto，
 *     文案长短不一时不会破版。
