Here's a complete HTML document for 看球网—a free live sports streaming platform covering the NBA, Premier League, Champions League, and more.

- **Sticky header actions**: A pulsing “一键收藏本站” button uses Ctrl+D prompts, while the right-side latency monitor and “一键秒开” button simulate line optimization.
- **Hero theater**: The giant live player shows a sample football match with a picture-in-picture window for a second game, plus a rolling danmaku feed that pauses on hover.
