   deyingding · 落地页样式（index.php 的 page_head）
   ----------------------------------------------------------------------------
   原先是 index.php 里一段 185 行的内联 <style>，写死了 148 处深色值，
   且这个外壳从不加载 static/css/tokens.css，导致落地页：
     · 与 tpl/layout.php 的内容站前台两套配色（同站不同脸）；
     · 完全不参与换肤。
   现改为引用全站设计令牌，颜色只在 tokens.css 里定义一次。

   加载顺序要求：tokens.css → landing.css（顺序反了 var() 取不到值）。
