   IntegrytasGroup — site stylesheet
   Brand: Dark Navy #1E2D3D · Deep Blue #2D3E52 · Steel Gray #8A98A2 ·
          White #FFFFFF · Burnt Orange #E8712A
   Typography: Inter, two weights only (400 / 600) per brand guidelines.
   The orange→gold gradient is reserved for the logo mark and is never
   reproduced in UI chrome; the solid Burnt Orange is the only accent.

   Written MOBILE FIRST. Everything up to the 700px breakpoint is the phone
   layout, authored for the phone — not a desktop grid folded down. Desktop
   composition is layered on at >=700px and >=1000px.
