Testing Instructions

1. Go to the site editor.
2. Look for the search results template.
3. Try every one of them, and confirm that the search section looks like in Figma.
4. Go to yoursite.local/404 (replace yoursite.local with the site you're trying) and confirm that it also looks well on the 404 page.

Here is the difference between the pattern, and the search block:

search.mp4

In the pattern, the semi-transparent border is showing on the button,
I think that the border color should only be on the input. So it would need to be moved to the CSS in theme.json.

Since the default size for the block in theme.json is medium, the fontSize in the pattern markup should be removed.
