/* ==========================================================================
   DK System — Vigilance. Engineered.
   Premium design system

   Scaling: the root font-size grows fluidly with the viewport and every
   structural value is in rem, so type, spacing, images and the container
   scale together on large screens.

   Theming: every colour is a token. The dark theme is the brand default;
   [data-theme="light"] at the bottom of this file overrides the tokens and
   the handful of rules that need genuinely different treatment (product
   renders, brand logos, grain, glows) rather than a flat inversion.
