/* ==========================================================================
   WBC Software
   Palette derived from the WBC mark: petrol teal #064C53 on light.
   Surfaces are near-black nudged a few degrees toward the brand hue; the
   accent #A3C8CE is the mark's own edge tone, so both sit on one hue axis.
   Colour stays scarce — it marks the brand, never decorates.
