   Read off a ruler overlay on design/reference/09-contact.jpg at a matched
   1440 canvas (source is 1024 wide, so x1.406). The page wears the teal theme
   (D-009): --color-action and friends resolve to teal inside .theme-contact,
   which sits on <main> so the header stays identical to every page (D-052).

   Type is sized by measured width (D-049). The mockup face is condensed, so
   the smallest uppercase labels would fall below 12px by width alone; those
   are floored at 12-13px for legibility and noted where they are.
