Location Pin

Location pin, a smooth world-scale map pin 1 m tall: a rounded teardrop head 0.5 m across, 0.12 m thick, tapering to a point over a thin flat ring 0.3 m across on y = 0; the head's face holds a flat decal slot or kit glyph. The ring glows in the accent.

风格：low-poly, flat-shaded vertex colors, no textures, 3 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
