   Four of them: the landing page, the auth page, the signed-in shell
   (rail + page) and the page itself (head, body, foot). Nothing here styles a
   widget; it decides where widgets are allowed to sit and how wide they get.

   of the column: a form 800px wide above a .detail-group 612px wide above a
   table scrolling inside 470px, three different left edges down one page. The
   files had been patching that one element at a time — .profile-editor,
   .profile-card and .bzw-page each carry their own `width: 100%`, and this file
   had an EMPTY `.page-body > *` rule where the general fix was clearly meant to
   go. This is that rule.

   Children still centre, so anything with its own max-inline-size (a .card is
   26rem) sits in the middle of the column exactly as before; everything else
