Built-in modules and import maps demo!

This page demonstrates the use of:

• The built-in module std:kv-storage
• The import maps feature to provide polyfill fallback in browsers that don't support KV storage (including even in browsers that don't support import maps!)

Here's the actual demo. Be sure to check out the source!

Try it out in Chrome Canary with the Experimental Web Platform Features turned on in chrome://flags. There, both import maps and KV storage are present.

Then, try it out in Firefox, Chrome Stable, or Safari, and notice how the polyfill is being used! Magic!

(Can you help me debug it in Edge? It doesn't work, but shows no errors in the console.)
