/* Automating DNA — design system v2.
   Playbook: restraint x one signature device (the helix), huge tight type
   with an italic serif accent, real product in the first viewport, motion
   choreographed as one system, fast above all.
   Palette: deep navy + the returned brand blue (#58a6ff family).
   This blue belongs to Automating DNA only; InspectAI keeps its orange. */
