/* ============================================================
   CLOUDBORNE — SKY ENGINE
   Design system + styles for every screen.

   TOKEN SYSTEM
   ------------
   Color   Dawn Peach #FFB88C · Sky Blue #7EC8E3 · Deep Dusk #2B3A67
           Cloud White #F7F9FC · Sunset Gold #FFD97D · Ember #FF6F59
   Type    Display: "Fraunces" (warm editorial serif, used sparingly)
           Body/UI: "Quicksand" (rounded, soft, premium-casual)
           Utility: "Poppins" (HUD numerals, labels, data)
   Signature element: the hand-built layered hot-air balloon
   (canopy panels + rigging + basket + flame) reused everywhere —
   loading screen, menu hero, and customization preview all share
   one construction so the balloon reads as the game's mascot.
