Create a 3D model of a stylized minimalist keyboard with a soft, toy-like appearance. The keyboard has a thick rounded rectangular base in matte blue color. The keys are pill-shaped and rounded on top, arranged in a grid. Use three key colors: pale yellow for the center keys, navy blue for the left and right keys, and pastel pink for the space bar and corners. The overall look is smooth, plastic-like, and playful, with no sharp edges or fine details
