Pier Access Stair

Bolt-on timber stair run climbing from the beach to the pier walking surface, 3m wide to match the deck and rising exactly 1.2m over about 2.2m of run, chunky chamfered treads on two stringers with short posts.

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
