Slime Trail Decal

Slime trail decal, under 0.02m thick: a 0.7m-wide meandering ribbon of drying mucus 6m long, glazed and faintly iridescent silver-violet with a brighter fresh centre line, square-ended at the same width at both ends so trails chain into long wandering runs.

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
