   Values here are taken from the design handoff spec; they are final.
   Note: the raw brand pink (#FF4FBC) and cyan (#00C2FC) fail WCAG AA on
   white, so buttons use the darkened variants (#CC1C82 / #0098CE) and the
   bright originals appear only as accents or on the black contact section.
   Do not "restore" the raw palette colours on white backgrounds.
