/* =========================================================================
   GermanUSA Airbnb — Design Tokens
   =========================================================================
   Single source of truth for the design system. Every visual decision
   (color, spacing, type, radius, shadow, motion) is a CSS custom property
   defined here. Components consume these tokens and never hardcode values.

   Palette: German flag — Schwarz (black), Rot (red), Gold (gold).
   Refined for screen use (not pure flag values) to meet WCAG AA contrast.
