Paper Stack

Aggregate stack of a4 paper as a single low-poly slab with subtly uneven top sheets, with a height knob from a few sheets to a 0.1m ream and a state knob for square-edged, fanned askew, or clipped into a report with a spiral spine.

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
