All of this code runs specifically in the playground, so there is some really weird stuff going on in this PR. Apologies in advance.
This is slimmed down version of Lit stories and material-collection. Here's a summary of the changes:
- Lit stories
- Knobs use MD3 components and theming
- IE style renderer ripped out
- Unsafe style considerations are gone
- Stories for testing infra removed
- material-collection
- MaterialCollection is just LitCollection since we handle theming differently
- added theme-loader which syncs with the theme w/ rest of the page
- no textarea knob necessary since MaterialCollection is gone
- setUpDemo doesn't handle fonts and icons since we just load them in index.html
