Standing Water Pool

A shallow puddle of seeped water for a stone floor, a thin 0.02m flat blob about 1.4m across with an irregular outline that reads as it lying in the low flags, a dark still surface with a pale mineral tide ring at the rim.

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
