Glowing Rune Stone

A single dressed wall or floor stone about 0.6m square carved with a deep-cut angular rune, set proud of its course so it can be dropped into any wall face or flagstone tile, with a glow knob (dead grey, faint pulse, bright) and a hue knob.

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
