   Ghahreman — design tokens
   Ported 1:1 from the redesigned mobile app (`apps/mobile/src/theme/`): dark
   slate stage, lime-mint actions, gold for prizes/champions, sky blue for
   secondary. Colak Pro type, RTL fa. Names mirror the app's Figma variable
   collection (gray/*, Mint/*, Orange/*, Blue-sky/*) so the two stay in sync —
   when a value moves in `apps/mobile/src/theme/colors.ts`, move it here too.
   This file owns: @font-face, the color scale, gradients, shadows, radii, the
   fluid type scale, motion tokens, and a small element base. Section/component
   styles live in css/styles.css.

/* ---- Colak Pro (Persian) — the app's face. Two styles at one weight:
   Normal for body, Soft for emphasis/headings. Converted from the mobile TTFs
   (`apps/mobile/src/assets/fonts/colak/`) — no synthetic weights, the family
   simply doesn't ship them. ------------------------------------------------ */
