Why These Versions?

CSS clamp()

This modern CSS feature allows the time and score text to scale smoothly and responsively across different screen sizes. It's the primary reason for the baseline browser versions listed.

Screen Wake Lock API

This API keeps your device's screen from falling asleep while the clock is running. It is fully supported in Chrome, Edge, and Opera. On Firefox and Safari, this feature isn't available, but the app remains fully functional.

While the app may load on older browsers, you might encounter layout issues or reduced functionality. The versions above will ensure all features work as expected.
