Summary

Coming out of #417, need to handle this case

<script type="module">
  import '@evergreen-wc/eve-container';
</script>

or maybe even

<link href="/node_modules/prism/prism.css" rel="stylesheet"></link> 

Details

Otherwise getting this error in the console

Actually, in regards to Polyfills plugin I realize that I may be conflating two things here.

There is a difference between having a file with some code (the issue in #450 )

<script src="bare-import.js">

vs just some code (the issue here)

<script>
  /* some code */
</script>

We can easily feed <script> tags to Rollup, but pure JS (or CSS or whatever) code inside a <script> tag would have to be processed with something like acorn I think, kind of like we do with building up an importMap.

However, this was not something webpack was doing for us, so I think we should make the smallest concession here to support the immediate issue by making sure bare paths to node_modules can be resolved when included via <script> / tags with a src / href and track adding support for additional cases post 1.0 as they come up.
