Kerb Storm Drain Inlet

Curbside storm drain catch basin that drops into a 4m kerb run: a 1m-long concrete kerb block whose face carries a dark rectangular throat opening under the lip, with a flush slotted grate panel in the gutter beside it and a painted kerb-top mark.

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
