   MULTILUX — dark premium
   Near-black canvas. The logo's three colours used at full strength, as text
   and as structure.

   THE ARGUMENT FOR THIS DIRECTION, measured:
     on WHITE  — orange 2.7:1 · blue 2.4:1 · green 1.8:1   -> all fail as text
     on #0a0a0b — orange 8.0:1 · blue 8.4:1 · green 11.5:1 -> all pass easily
   Dark is the only canvas where Multilux's brand colours can be used freely
   rather than kept decorative. It is also where the low-resolution stock
   photography reads best: a dark field hides softness that white exposes.
