/**
 * itam.css — ITAM 产品详情页专属样式
 * 从 itam.html 内联 <style> 提取（2026-06-17）
 *
 * 选择器前缀：body.itam-page（特异度 0,2,0，确保覆盖 mobile.css 通用规则）
 * 加载顺序：product-detail-fix.css → itam.css → iconfont → mobile.css
 *
 * 断点：
 *   默认  → PC（1280px+）
 *   @media (max-width: 1279px) → 平板 iPad
 *   @media (max-width: 767px)  → 手机 H5
 *
 * 注意事项：
 *  1. @keyframes 命名为 itam-cta-gradient-shift（避免与其他页面冲突）
 *  2. PC 的 .product-cta-content width:1280px → width:100% + max-width:var(--content-max-w)
 *  3. iPad 块所有属性加 !important，防止 mobile.css 通用 !important 规则在 375px 泄漏
 *  4. H5 块所有属性加 !important，覆盖上方 iPad 块（max-width:1279px 包含 375px）
 *  5. iPad/H5 的 .product-cta-title 添加 white-space:normal，覆盖 PC 的 nowrap
