Match Ball

Match ball with a panel knob = football (a 0.22m faceted sphere read as white panels with dark accents), rugby (a 0.28m prolate ball with a raised seam and a pebbled grip band) and training (a plain single-tone moulded ball with a printed size ring).

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
