   Ground #0E0E0E · accent Pantone Yellow C #FEDD00 · Acumin Pro (kit zbp5rqc)

   Acumin Pro weight map in Adobe Fonts:
     400 Regular · 600 Semibold · 700 Bold · 800 Black
   Display type uses 800. There is no 900 in the kit — do not ask for it or
   the browser will synthesise a smeared fake.

   Mark usage rule: the fill must contrast with the ground.
   Never the yellow mark on white (1.35:1 — the negative-space cuts dissolve).
