/* ==========================================================================
   TT Core — 线路详情页版式 "T2"（Claude 设计稿 tour-detail-option-b，2026-10-13）
   · 用户 Mark 2026-10-13 拍板：版面严格照 Claude 稿，只动「违反 SEO 冻结 / 红线」处。
   · 本文件只服务 tt_layout=t2 的线路页（由 tt_tour_t2_html() 输出，条件加载）。
   · 字体：Fraunces + Public Sans 均为 SIL OFL 开源，本地自托管 —— 零 Google 依赖。
