/*
 * Unbound 统一登录 · 自建 Experience 页面样式（方案 2：一份代码 + appId 分支）
 *
 * 设计 token 两级：
 *   1) index.html 的 resolveTheme() 按当前 appId 注入品牌色（--brand 系列）；
 *   2) <html data-family> 决定整套设计语言 + 官网同款页头页脚：
 *        - 缺省 / browser ：对齐 https://browser.unb.ink （浅色 Apple 风 + 该站页头页脚）
 *        - unb           ：对齐 https://unb.ink （深色工作室风 + 该站页头页脚）
 *
 * 页头/页脚结构由 login-unb8.js 按 window.UNB_CHROME 渲染，本文件的组件类名与之对应：
 *   浅色（浏览器站）  .brand-logo / .nav-links a / .cta--ghost|primary / .footer-grid / .footer-bottom
 *   深色（工作室站）  .brand-mark / .nav-link(em+span) / .nav-cta(.cta--ghost) / .lang-switch
 *                     / .footer-top / .footer-prods / .footer-bar
 *
 * 品牌色优先级：应用级 color.primaryColor > 主题表 accent > 此处缺省紫 #6139F6。
 * 素材走同源 /branding/*（nginx 已挂 location ^~ /branding/）。
 * 文件名带 -unb8：Cloudflare 对静态资源按 URL 缓存 7 天，改内容必须换文件名才生效。
