/* ==========================================================================
   Sanaa Guild — sanaaguild.com
   Built on the IKEA design system (designmd slug: "ikea"), retinted to
   workshop tones: raw timber, steel blue, signal yellow.

   System traits preserved:
   - Deliberately limited palette: one dominant colour + near-black surface
     + white, plus a single high-voltage accent (here: signal yellow).
   - background token == primary token: full-bleed primary-colour hero band.
   - Flat. No shadows anywhere; depth comes from colour blocks and weight.
   - Single 8px radius token (radius.sm) used everywhere.
   - Hairline borders in the near-black border token.
   - Shallow 3-step type hierarchy, bold weights, negative tracking.
   - Non-linear spacing scale 4 / 16 / 20 / 24 / 36 / 120 / 140.
   - Motion: 200 / 500 / 700ms, ease-out only.
