/* 多品牌着陆页样式（7 站共用，品牌无关）
 *
 * 2026-09-17 从 resources/views/landing/brand.blade.php 的内联 <style> 抽出：
 * 那 15KB 里只有十几行是品牌动态的，其余与品牌无关却跟着每个响应重发、且无法被浏览器缓存。
 * 拆分后本文件可缓存、7 站共享；**品牌色板全部留在视图的内联 :root 块**（唯一主题契约处）。
 *
 * ⚠️ 本文件内**不得出现任何 Blade 插值**，也不得写死品牌色 —— 一律走 var()。
 *    原来散在样式里的 3 处插值已收进内联 :root：--bg-alpha / --grad-promo / --code-bg。
