/* ==========================================================================
   PRISKILA INVISIBLE GRILLS — Design System
   Concept: "The Arch Viewport" — the halo of grill wires that frames a view
   in the Priskila mark, carried through as the site's structural motif.
   Secondary language: the "spec sheet" — hairline rules, grade badges and
   material call-outs that speak to the SS-316 certification the brand
   leads with.
