   Palette derived from the brand mark: navy book, orange pencil, slate lines.
   Signature: a 4px orange rule — the pencil — marks the start of every section.
   Accessibility note: brand orange #F07B24 is only 2.78:1 on white, so it is
   used for graphics/large display only. Text-on-colour uses navy or #C2570A.
