Basic usage question

I'm still learning the set of technologies here (e.g. lit, typescript, tailwind, and postcss) and I'm having trouble using this postcss plugin.

I checked in my sample code here - https://github.com/pathofleastresistor/postcss-lit-example.

I was expecting ```npm run build1``` from my package.json to be what's needed to get your example working, but my main.js doesn't include the transformed css.

Did I miss something?
