/* ---------------------------------------------------------------------------
   Sway games-integration docs — shared design system.

   Derived from the mobile app's actual values, extracted from source. The
   mobile app has NO theme or token file: every colour is an inline hex literal
   spread across ~30 style files. This stylesheet is the first place those
   values have been consolidated, so treat it as a reference for the real
   tokens, not as an invention.

   Source of the values below:
     apps/mobile/src/app/dashboard/index.tsx      (gradients, chart colours)
     apps/mobile/src/app/dashboard/styles.ts      (text, tabs, bars, cards)
     apps/mobile/src/components/Header/styles.ts  (menu lines, shadow)
     apps/mobile/src/utils/responsive.ts          (spacing, radii, type scale)
     apps/api/prisma/seed/data/trust_categories.json (category colours)
