The guided installer covers apt, dnf, pacman and sysext boxes, but only the
install hub mentioned it — a reader who lands on /docs/ubuntu from a search
never learns the whole page has a one-liner. Put the same block above step 1
on every page the script actually detects, and leave NixOS, SteamOS and
Windows alone: the script refuses those and points at their pages.
Also list Omarchy on the hub cards and in the quickstart table. It was added
to the sidebar with #428 but never to the two pages that route people there.
