   页脚 —— 多页共享的那一部分

   2026-08-05 建的。首页与案例页原来各有一套独立实现，改动不会同步，
   所以把真正共享的排版规格收进这里，并由工具检查内容是否一致。

   这个文件只装**真正共享**的东西：
     .foot-row      内容行的排布（左版权、右标语）
     .foot p / a    页脚文字与链接的规格（原来在 landing.css 和 case-detail.css
                    里各有一份，值一模一样，现在合并到这里）
     .foot-slogan   右侧标语
   两页都要 link 它。检查这一点也在 tools/check-footer.py 里。

   ⚠️ **`.foot` 本身的规则不在这里**，故意的。两页的外壳合理地不同：
        首页    border-top:1px solid var(--edge)；背景由 .sec-dark 给
        详情页  border-top 透明 + 显式 background-color:var(--paper)
      它们各自留在 landing.css / case-detail.css 里。
      别把 .foot 也搬进来「顺手统一」—— 那会改掉其中一页的收边。

   ⚠️ 颜色全走语义令牌。页脚挂着 .sec-dark，令牌在那个作用域里会翻转，
      所以这里一个字面色值都不能写。
   ══════════════════════════════════════════════════════════════════════════ */

/* 内容行。用 flex 而不是靠外层栅格的 grid-column —— 外层在两页是不同的容器
   （首页 12 列栅格 / 详情页定宽块），flex 行在两种容器里表现一致。
   ⚠️ grid-column:1/-1 是给首页那个栅格容器用的；在非栅格的父级里它会被忽略，
      不会有副作用，所以两页可以共用同一段标记。 */
.foot-row{grid-column:1/-1;
  display:flex;align-items:center;justify-content:space-between;gap:24px;}

.foot p{font-size:11px;letter-spacing:.1em;color:var(--text-faint);margin:0;}
