One button that toggled H2, so a document could hold exactly one weight of heading — and the levels the
site's sanitiser already accepted were unreachable from the editor that writes for it.
Three buttons rather than a dropdown: they are toggles like everything else on the bar, the active one
answers "what is this line", and a select would hide that behind a click.
A level is a rank in the outline and never a size. What each draws at is the site's — three of the four
type roles, in the prose rules — so the Layout section stays the one place type is sized.
`[open]` H1 is offered because it was asked for, and a page that already has a title now has two. That
is an outline a search engine reads as two documents, and it wants a rule about where H1 belongs before
this gets used much.
