   1. The CV strip: a centred two-line headline, the second line muted and
      stepped in to the right, with the "View my CV" pill underneath.
   2. Contact: the last section before the footer. Three channels side by
      side, each a centred label over its link.
   Loaded after style.css, which holds the base .contact-strip rules and
   the CV focus state (the waving sheet behind the headline).
