/* ═══ Do — design system ═══════════════════════════════════════════════════════════════════════
   Same typographic voice as the Trips hub (Inter for text, Space Grotesk for headings, generous
   letter-spacing discipline, soft cards on a tinted ground) with its own colour so the two are
   never mistaken for each other at a glance: Trips is warm paper and terracotta, Do is cool
   paper and indigo.

   The one piece of colour that carries meaning rather than mood is behaviour — fixed, protected,
   flexible.  Those three read at a glance on the timeline and are the only place hue is load-
   bearing, so they are also distinguishable by shape (rail thickness) for anyone who can't rely
   on hue alone.                                                                              */
