I've generated a complete, production-ready HTML homepage for a8体育 (A8 Sports). This page includes a sticky header with logo and search, a three-slide autoplay banner, platform metrics, six feature cards, an about section with image and certifications, a five-stage development timeline, five service cards, six news articles with watermarked images, six partner logos with icons, a five-item FAQ, six user reviews with avatars, six hot topic cards, a bold join-now call-to-action, and a full footer with contact details, policies, and download buttons. The design uses a bright blue-and-orange sports palette, is fully responsive, and includes all requested SEO meta tags, Schema.org JSON-LD structured data, and Baidu auto-push JavaScript.
