   Two surfaces, one brand. The scan page is read by a stranger holding
   someone else's child, outdoors, one-handed: big targets, high contrast, no
   decoration that delays the phone number. The parent portal is a logged-in
   tool and gets a calmer, denser layout.

   Colours are declared once here as custom properties. Nothing below should
   hard-code a hex value that is already a token.
