/* ==========================================================================
   MURASHKIN STUDIO — Design System
   Art direction: "exaggerated minimalism" — oversized fluid type, generous
   whitespace, high contrast, calm & professional. Light theme primary with
   one dark section for rhythm. Orange = CTA only, purple = secondary detail.
   ========================================================================== */

/* --------------------------------------------------------------------------
   1. FONTS
   Headings: "Unbounded" (500, 700) — distinctive, techy, full Cyrillic.
   Body: "Inter" (400, 500, 600) — chosen over Manrope because Inter ships
   a wider Cyrillic + Cyrillic-ext subset, has superior hinting and optical
   legibility at 16–18px UI sizes, and its neutral grotesque voice balances
   the loud, decorative Unbounded without competing with it.
