/* ===================================================================
   联系方式组件样式（contact.css）
   -------------------------------------------------------------------
   由 lib/siteContact.js#patchContact() 注入到全站页面，与 style.css 配合。
   刻意独立成文件（而非并入 style.css）：新文件不存在浏览器缓存问题，
   全站换联系方式时用户无需强制刷新；同时 style.css 不必再被反复改动。

   组成：左侧联系栏 .twc-rail / 右侧顾问卡 .twc-card / 页脚二维码横条
        .twc-qr-band / 顾问弹窗 .twc-modal / 页脚联系列 .twc-footer-col
   依赖 style.css 的变量：--red --red-dark --red-deep --gold --gold-light
        --ink --ink-soft --line
