Here is a complete, production-ready HTML page for the 雷速体育 live sports platform, featuring a real-time scoreboard, multi-sport filtering, and a news feed.
### Live Match Dashboard & Interaction Design
The page works as a dense, real-time control room for football, basketball, tennis, and esports.
- **Three-column layout** – A narrow left rail offers sport filters and league shortcuts; the wide center holds four focus match cards and a filterable match grid; the right column shows a hot ranking and scrolling news.
- **Focus match cards** – Each card displays live score, time, and stat lines, with a small animated pitch or court area that uses moving dots to suggest in-play action.
- **Filter and sort controls** – You can narrow the card grid by sport using the left rail or the tab bar, and reorder cards by time or popularity with one click.
- **Score flashing** – Scores update every few seconds; a quick red flash draws attention to changes in the match grid and the clock for football matches advances in real time.
- **Encore and schedule panels** – Finished matches show final results and key stats, while the 7-day schedule lets you switch days and follow individual fixtures.

**Optimization Tip:** You can replace the static score and match data in the HTML with real API calls, and update the schedule array inside the script to reflect actual fixtures.
