   DPDPA.support — Design System (site.css)
   "dpdpconsultants BONES, Apple SKIN."
   Light-first, generous whitespace, large clean type, restrained
   navy + single red accent. Dark cinematic bands are opt-in via
   `.section--dark`. Mobile-first. Tokens → base → layout →
   components → responsive. Owned by the design-system foundation.
   Page agents consume only — change the SKIN, not the contract.
