#241 made the host sections pills: on a desktop they took two lines,
unlike the breadcrumb the pages had. computes/host_nav.html is the
breadcrumb again, one line at 1200 px and wider, still shared by the
eleven host pages: the section's own page is its bold item with
aria-current="page", an item page (a pool, a network) links its
section in bold with aria-current="true".
The capacity lines were kept on one line, made for the Computes
table: in the overview's narrower cards a long memory line ran out of
its card. They now wrap.
Eleven host pages (overview, instances, storages, networks, interfaces,
nwfilters, secrets and their item pages) each carried their own copy of
the links to the host's sections, as a breadcrumb: the sections are
siblings, not a path, and on a phone the separators were left at the
start of wrapped lines. The item pages marked no section at all.
computes/host_nav.html is the one nav, labelled "Host sections": pills
that wrap, the page's section marked active, with aria-current="page"
on the section's own page and "true" on an item of it.
