   WARDYN TECHNOLOGIES — DESIGN SYSTEM
   Conforms to Wardyn Technologies Ltd. Brand Guidelines V1.0 (2026).

   §05 Colour   Monochrome by default. Signal Red marks contact only.
                Target ≈ 90% neutral / 10% red.
   §06 Type     Orbitron 900 — display only, caps always.
                Archivo   — headlines 700–800, body 400–500. Never skewed.
                IBM Plex Mono — labels, captions, specs. Tracked wide, small.
   §02 Logo     Fixed geometry. Vector only, never redrawn.
   §03 Quiet    Nav, footers and UI chrome use the quiet variant.
