Random thought: does defining the icon by ID like this affect tree shaking for react-lucide?

[devinvillarosa]

I don't think so: https://lucide.dev/guide/packages/lucide-react#one-generic-icon-component

I think the next followup PR, we can create a list of Icons only available to the ui using its direct imports.

And then we can create a Record of ui-v2's Icons and export it that way

Gotcha, that sounds like a good way to abstract icon stuff and make it easy to introduce icons from other sources.
