For your consideration, some example page patterns. This is a very quick and developer friendly way to create full pages in Storybook, you can reuse stories (see Article story) or completely static (Homepage story is a copy of prototypes).

There are added benefits like a11y tests for the full page, interactions tests for forms, quick theme switching, viewports etc.

Also, we don't have to maintain another app like prototypes. We should do a prototypes pages more like a started kit because developers will use it as such.

I've not included the pages in a Canvas block but instead created an example codeblock with some pseudo page layout code. The idea is to elaborate on page structure and leave the pages to fullscreen examples.
