   Riso print. The palette comes from the lab's own risograph-style
   art (the tick, Lil Labs, SxAffold): fluorescent pink, cobalt blue
   and marigold on cool paper, with nasalab lavender for surfaces.
   The one loud move is the homepage headline, printed in two inks
   with a hairline slip of registration. Everything else stays quiet.

   Change colours and fonts here; nothing below hard-codes them. */
