   Mimelax Design System — Brand tokens (single source of truth)

   Mimelax is a children's learning + bedtime app for ages 3–7.
   Two coexisting moods, one brand:

   • Day mode  — playful, joyful, candy-bright primaries on cream.
                 Used for game cards, the home dashboard, marketing.
   • Night mode — calm, storybook, deep indigo→violet with amber gold.
                 Used for "Bugünün Masalı" (Today's Tale) bedtime flow.

   Type pairs Quicksand (rounded sans, UI + headings in day mode)
   with Fraunces (warm serif, used for storytelling + editorial moments).

   Source of truth lives in src/app/globals.css in the codebase. Keep this
   file in lockstep when tokens change.
