Art style: 3D Pixar-style animation.
A cheerful baby in a colorful nursery holds an orange wooden triangle. He wears green and blue overalls. Behind him is a wooden puzzle board and shelves with toys. Warm, bright lighting fills the room, highlighting educational posters on the wall. The word 'TRIANGLE' appears in large, colorful letters.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar-style animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar-style animation". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Pixar-style animation" idiom, not in any other medium.
