/* ============================================================
   七格美国仓 · 产业合伙人计划(/partner.html)专用样式
   ------------------------------------------------------------
   - 仅本页专用;nav / footer / 色变量 / 基础重置 一律在 shared.css。
   - 类名统一 pt- 前缀(与 shows- / mat- 的分页前缀惯例一致),
     不复用 index.html 内联的 .section / .sec-title —— 那是首页的页面专属类,
     跨页复用会变成两处维护。
   - 遵守平衡铁律(2026-07-12):四边等宽 1px、无单边色条、无渐变装饰条;
     层级靠留白 + 字号 + 衬线对比。同色系背景过渡不算装饰条。
   - 主色锚定:金 = 门槛 / 价值 / 落地事务;青 = 能力 / 服务 / 流程。
