   DECIMA DESIGN TOKENS
   Single source of truth for the design system.

   These are NEUTRAL PLACEHOLDERS. When the Decima brand/design
   system is ready, swap the values here (colours, fonts, scale)
   and the whole site updates consistently. Prefer editing tokens
   over hard-coding values anywhere else.
