/* 快跑AI 门户样式
 *
 * 设计语言（对齐主流欧美 SaaS：Supabase / Vercel / Linear 这一路）：
 *   · 主按钮是近黑色，不是饱和色块；强调色只用在链接和少量高亮上
 *   · 用 1px 描边区分层级，而不是堆阴影
 *   · 标题紧排（-0.02 ~ -0.04em）、行高 1.05 左右
 *   · 正文用中性灰，不用彩色文字
 *   · 图标一律内联 SVG，不用 emoji 当图标
 *   · 留白优先：区块之间 96–140px
 *
 * 2026-09-27 改版：
 *   · 首页首屏改成「怎么用」：接入地址 + 三步 + 发布流程窗口，不再放宣传口号
 *   · 首屏下面放真实用例截图（用 HTML/CSS 画的小应用界面，不上位图）
 *   · 子页面去掉「文档式」的大标题，收成一条紧凑的页面条（page-bar）
 *   · 整体加层次：柔和的背景光、更克制的阴影、更紧的排版节奏
