A browser-support component

Using the web platform features data behind MDN & Baseline, along with some of the Baseline language and icons. I imagine there are a lot of improvements that could be made here, and I'd be very glad for suggestions and improvements!

• Stand-alone component, without Lit or other frameworks
• Responsive to font sizes, available space, and light/dark schemes
• Allows customization of the title markup (h2 by default)
• 'Newly supported' web features show a timeline towards broad support
• Allows for simple light-dom fallback & progressive enhancement

Progressive Enhancement
