Recommendations
- Always test on the latest versions of Chrome, Firefox, Safari, and Edge.
- Provide polyfills for Flexbox and Grid when supporting older browsers.
- Use feature detection (e.g.,
if ('serviceWorker' in navigator)) instead of user‑agent sniffing. - Gracefully degrade media formats: provide WebM alongside MP4.
