   Palette:  cream ground, teal primary, coral for wrong/retry,
             mustard for rewards, ink for text.
   Type:     Fraunces for titles and game names, Plus Jakarta Sans for
             anything a child reads as an instruction.
   Rule:     one accent per screen. No gradients. No blurred shadows.
             Nothing animates unless it was touched.
