   Palette comes from the logo's steel blue, set on deep ink with a warm
   gold accent ("Lighting Darkness").

   Shape language: "almond" corners taken from the eye in the logo. Boxes
   get a big radius on two opposite corners and a tight one on the other
   two; on hover they flip to the other diagonal.
