I'm starting to notice this is actually part of a bigger inconsistency in how components are actually typed. For instance the Divider has its size typed, but not its variant:

ui/src/runtime/types/divider.d.ts

Lines 1 to 3 in d0e626c

	import type { divider } from '#ui/ui.config'
	export type DividerSize = keyof typeof divider.border.size.horizontal | keyof typeof divider.border.size.vertical

Personally I would merge this to simply fix the related issue, then in a different PR experiment if it is actually possible to fix all typing. Or is it even worth considering v3? @benjamincanac WDYT?
