   IDENTITY TOKENS, all derived from the app and its mark:
   - ground #121417 and panel greys from the app (colors.xml), amber #FFB020 = the mark's jaw,
     the selection and the measurements in the app
   - the cube greys of the mark for secondary surfaces
   - the JAW (an open bracket) is the atom: section labels, bullets, the measure ticks
   - type: Space Grotesk for display, Inter for body, JetBrains Mono for every number that is a
     dimension (as on a drawing) */
