   GNY Hukuk Bürosu — v3
   Design tokens + base system.

   Direction: cinematic, restrained, Apple-product-page-inspired scroll story.
   Brand-locked: logo (teal + gold variants), Cinzel (display) + LBRITE (body).
   Palette derived from the two existing logo marks — deep teal ground,
   gold as the singular accent — never reintroducing v1's warm-editorial
   parchment tones or v2's Strata Rose purple/duotone.
