   Light, quiet, image-led. The photographs carry all the colour; the
   interface stays monochrome and gets out of the way.

   1. Tokens          - colour, type, spacing, motion
   2. Reset & base
   3. Layout          - wrappers, sections, grids
   4. Typography
   5. Components      - header, nav, buttons, hero, cards, facts, credits,
                        quotes, events, gallery, lightbox, timeline, CTA, footer
