Cute Eco Robot Pixel Art Mascot

Create a centered full-body pixel art mascot robot on a clean {argument name="background" default="plain white background"}. The character is a cute chibi eco robot with a cream-colored rounded helmet-like head and body, dark black face screen, and green plant-themed accents in a retro 16-bit/32-bit pixel style with visible square pixels, crisp black outline, and soft shaded highlights. The robot has exactly 2 large glossy green eyes with white heart-shaped highlights, a tiny white smiling mouth, exactly 2 round green side ear pods, exactly 2 green sprout leaves growing from the top antenna, and a small green forehead panel decorated with a white sprout icon plus 2 white dots. The body is compact and rounded with a square green chest panel showing a white sprout emblem, exactly 2 arms with green joints, the left arm raised in a friendly wave with a small green segmented hand, the right arm hanging down with a chunkier cream forearm and green hand, exactly 2 short legs, and exactly 2 cream-and-green boots. Use a warm palette of {argument name="main body color" default="soft ivory cream"}, {argument name="accent color" default="leaf green"}, deep black for the face visor, and subtle yellow-green highlights. Make the mascot adorable, symmetrical, front-facing, isolated, no text, no watermark, no extra props, high-resolution pixel art with a slight grid-like pixel texture.
