   Krignal — print edition
   A two-colour risograph treatment: warm charcoal paper, one vivid yellow
   doing all the work of light, near-black for weight. Layered over main.css,
   so every rule here is a deliberate departure from the painted edition.
   Colours are sampled from the generated poster art.
