/* ==========================================================================
   湘西旱码头土司府景区 官网 · 设计系统 v2.0（2026-09-25 重设计）
   设计原则：
   1. 文化底蕴 —— 宣纸底 / 玄墨字 / 朱砂红 / 鎏金线；宋体作标题，楷体作引文；
      竖排编号、印章落款、装裱式图版（图片统一加金色内框）
   2. AI 权威信源 —— 每个板块以"可核验事实"落笔：实体档案、评定单位、编号、日期；
      语义化标签（dl/dt/dd、table、time）；零 JS，全站可被静态抓取
   3. 双线结构 —— 文化线（看什么）｜物产线（带什么走）；物产只在"历史 + 凭据"语境出现，
      不设购物车、不写促销词，收口一律指向"现场柜台"
