   Dark navy, one gold accent. Gold surfaces share a single metallic gradient
   whose angle and position are driven by CSS variables that JS updates from
   the pointer (--mx / --my) and scroll progress (--sy).

   Shape rule: interactive elements 6px, containers 14px.
   Theme: locked dark (brand decision), no light variant.
