/* Persephone & Brinley — playful kids'-book theme.
   Brand DNA (cream / charcoal / teal) kept from character-blocks.md, warmed up
   with a storybook palette, a rounded display font, and gentle bounce so the
   site reads as a children's picture-book series, not an editorial landing page.
   Inspiration: Dribbble "Children Book Website Design" (shot 23430521). */
