Sandbox

Square timber sandbox about 2x2m with wide sleeper sides doubling as seats and a lightly heaped faceted sand fill inside its frame; lid knob (open, half-slid cover boards, fully covered) and a fill knob from fresh flat sand to dug hollows with a mounded pile.

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
