<https://s.mj.run/nqzOpRHvGrg> Design a capsule-shaped tree pit set into a stylish, modern sidewalk. The tree pit should have clean, geometric lines and an overall minimalistic aesthetic, similar to the base structure shown in the reference image. The tree pit is slightly raised, with smooth beveled edges and a subtle curb around its perimeter. The materials used should feel contemporary, like polished concrete or brushed metal, blending seamlessly with the surrounding sidewalk. The sidewalk itself should be urban and sleek, with subtle texture and pattern, fitting a city environment. Incorporate the tree within the pit, featuring a slender, elegant trunk that contrasts with the solid, smooth base. The setting should give off a modern, metropolitan vibe with clean lines and a focus on functionality and design integration. --niji 6
