/* ==========================================================================
   AURORA'S SUMMER ADVENTURE — STYLESHEET
   A magical, cosy, game-like interface for a 6-year-old learning explorer.

   DESIGN SYSTEM
   Colour   : Sky #BFE8FF -> Dawn Lilac #F1E3FF (background), Sun Gold #FFC94A
              (primary/CTA), Petal Pink #FF9EC4 (secondary/heart accents),
              Meadow Mint #7FE0C0 (success), Plum Ink #4A3F6B (text).
   Type     : one rounded, friendly system font stack used for everything —
              display vs body vs label roles are carried by weight, size,
              spacing and a soft "sticker" text-shadow, not by mixing
              families (keeps the app 100% offline-safe, no web fonts).
   Signature: the "Adventure Path" — a dotted trail with little paw/footprints
              that appears mini on Home, full-size linking quest cards on
              Today's Adventure, and stretched across the whole summer on
              the Treasure Map. One motif, three scales.
