Doraemon's visual language is pure Showa-era manga joy — thick black outlines, flood-fill primary colors, and relentlessly rounded geometry drawn from the character's circle-constructed body. Every element radiates kindergarten warmth: cyan-blue skies, white belly surfaces, red collar accents, and pink Anywhere Door portals.

This system translates half a century of children's manga craft into interface tokens — soft corners everywhere, bold outlines on every component, a bright daylight palette that never dips into darkness, and typography with the chubby hand-drawn quality of comic lettering.
