Prebuilt layouts

[kyranb]

So I understand that Flux is a composable component library (it's amazing), but it could benefit from more prebuilt “application shells” or layouts to reduce the time spent customising Tailwind for common use cases.

Examples of some layouts that I've found myself building:

1.	Right-hand pane: For contextual details (e.g., customer info in a CRM, help desk or Stripe).
2.	Second-level navigation: An inner/vertical/secondary menu.
3.	Split view: A split-view to show two separate things at once like an inbox/chat list (list on one side, details on the other).
4.	Dashboards: A grid-based layout with different sized cards.
7.	Multi page form layout, some kind of indicator or progress between multiple steps of a form.
