/* ========== PetLane - Standalone Pages ========== */
/*
   独立页面样式体系：About / FAQ / Contact / Order Tracking
   以及政策类页面 Shipping / Returns / Terms / Privacy（正文来自后台）。

   设计要点
   - 报头（masthead）与正文分离：报头用品牌奶油色通栏铺底，正文收成单栏阅读宽度。
   - 政策长文用「要点速览 + 粘性目录 + 正文」三件套，避免 8KB 条款变成一堵墙。
   - 章节标题前的爪印标记是本站的视觉签名（Material Symbols 已在站内入队，无需新资源）。
   - 颜色/字体一律复用 main.css 的 --petlane-* 令牌，不引入新色值。
