Remove opinionated settings from block markup

[mikachan]

As TT3 is focused on style variations, it would be good to remove as many opinionated styles from the block markup as possible. There are a few places where this is happening, but sometimes it can be difficult where unique styles have been required. Here's an example of where we have done this previously: #31

This issue is to track where we could consider moving these settings, and encourage discussion around this for each area:

• 404 pattern: Moved 404 size opinion to theme.json #93
• Search template: Search and archive templates: update spacing #103
• Home template: Moved sizing opinions from home to theme.json #94

I agree 404 can become much smaller:

About Search and Home, I'm not sure. What changes do you think could be done to make it less opinionated?

I don't see that the xx-large size has been used anywhere yet. Would it make sense to use that value, but maybe crank it up a bit? I'm actually keen to keep the value on the 404 page (font-size:clamp(4rem, 40vw, 20rem) or something close to it) for xx-large (which feels like "the upper end of sizes we should create").

I didn't notice any opinion in the search template that we might want to relocate (other than some spacing bits that are already being addressed in #52

I'm going to close this, as I think we've currently removed as much opinion as possible from the templates. Please open another issue if you spot anything similar.
