/* ADR-7513:品牌段落组件,首页与价格页共用(从 home.css 原样移出,类名不变)。叠在 site.css 与 site-sections.css(眉题、收尾带)之上,
   页面自己的样式表在它之后。新介绍页拼这些组件,不另写一套:
   · 区块节奏与标题:--home-section(112px,窄屏 72px)、main h2 用 --home-h2;任意区块加 .brand-block 即得同一节奏。
   · .offer-cards / .offer / .offer-kicker:白卡(基础样式在 site.css);.point-icon:40px 琥珀淡底图标块。
   · .trust-grid / .trust-card / .trust-num:大数字卡(.trust-grid.is-four 四列)。
   · .faq / .faq-item:居中 860px 折叠问答,自绘 +/−。 */
