Style book: creating landing page view

[ramonjd]

What

Create a new "landing page" view for the style book to display common theme blocks (and one day patterns 🤷🏻).

The requirements as stated in the parent issue are:

A “Landing” tab that would serve as the landing page of the stylebook: a page displaying only blocks that more commonly and immediately are able to represent the theme.

The landing page would be useful for the current iteration of the Site View, which does not currently feature tabs. It serves as a quick glanceable "poster view" for the site style guide:

How

It will very much depend on the outcome of discussions in:

• Dedicated Styles Screen #66376

There are a few open questions:

• What is the current use case for this view? When and where would it appear?
• What should appear there? What does "more commonly and immediately are able to represent the theme" mean?
• Can themes add their own blocks/patterns to the landing page? If so how? There would have be a special category or register function. For the former, blocks only have one category as a string. Should blocks/patterns accept subcategories, or an array of categories or some other flag?
  • Assuming "yes" to the above question, should theme patterns/blocks take precedence over Core's? How?
• How would the landing page handle classic themes, if at all?

Considerations

It's not yet certain how the landing view, which would presumably NOT contain a list of all blocks, would interact with a global styles panel in:

• Site editor: integrate global styles controls and style book preview into the styles panel  #65619

Perhaps the canvas's content could be dynamic, driven by navigation routes. For example, if the landing page is active and the user clicks on a block style, the canvas would load that block style.

It's not yet certain how the landing view, which would presumable NOT contain a list of all blocks, would interact with a global styles panel in #65619

I think the landing view would be ideal as a first glimpse of the stylebook when opening global styles! But given that #65619 also makes it possible to scroll specific blocks into view when looking at their global styles, we'd probably need a few different screens to switch between in that view.
