I’ve done a few different things, some different presentations, web mockups etc. They all look more or less identical out of the box, and in every single case of a presentation, Claude Design has zero concept of layout boundaries, happily making slides that expand 200% or more out of the visible viewport (I have a lot of content and it just can’t figure out nice ways of presenting it).

There’s still value in it for me, I get decent enough output to convey my intent and I sometimes manually tweak the HTML.

Defining fonts is a good way to at least not get the same typography as everyone else.
