   AheadWise design system: "the instrument"
   One type family (Archivo) used in three widths, cool neutrals, a single signal orange that marks what AheadWise
   measures (the needle), and semantic verdict colours that are never used for decoration. Hairline rules carry tick
   marks like a measuring scale. Documented live in system.html.
