Lane-marking-decal

Lane marking decal spanning the full 4m module, a set of thin flat dashed centre-line stripes under 0.02m thick that sit flush on the road tile so runs continue across tile seams, flat yellow-white.

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
