The way down the tree is the link at the foot, not an arrow that follows

0.5.3 put the same link in two places: in words at the foot of the
page, and as an arrow fixed at the left edge half-way up the screen.
The arrow stayed with the reader the whole way down a page to offer
what the foot offers where they end up anyway. It is removed; the foot
link and where it leads are unchanged.

+- The way down the tree is the line at the foot of the page and nothing else. The arrow fixed at the left edge, which 0.5.3 added beside it, is gone: it followed the reader down every page to offer something the foot already does.

 ## 0.5.4 (2026-09-29)
 
 - Accounts the content mandates, made at start (`src/seed.rs`). Every person a page names as `responsible` gets a Kanidm account if they have none, and a mail in the site's language saying they are listed as responsible for asking that question, with the link to sign in; `RESPONSIBLE_GROUP` puts them all in one group (people who already had an account are added without a mail). `SEED_ADMIN_EMAIL` (and `SEED_ADMIN_NAME`, `SEED_GROUP`) invites the first person into the site's most privileged group - the group whose desk may invite into the most groups - so a site with its own Kanidm has someone to invite everyone else. Both happen once per address and group (`portal_seed`), side by side, and each tries again a minute apart, twenty times, while Kanidm comes up. The responsible are gone over again whenever the content changes (`portal.content.reloaded`, published once new content is in place), so a new page's person is set up without a restart - and someone the content has stopped naming leaves `RESPONSIBLE_GROUP` in the same pass, if portal is who put them there.
