- Epic Games Support (Experimental): Matches Epic Games titles with Steam AppIDs to show compatibility info.
- Performance Focused: Uses caching and request batching to minimize API usage.
- Visual Clarity: Color-coded badges matching the official ProtonDB theme.

- Steam: Extracts the AppID from the URL or data attributes and queries the ProtonDB API.
- Epic Games: Since Epic doesn't expose Steam AppIDs, the extension searches for the game title on Steam API to find the corresponding ID, then queries ProtonDB. Note: This may occasionally result in mismatches.
