幼児用バランスバイクコース：縮小スケールの周回練習場

Show a miniature cycling circuit for very young children in a park. Render a smooth resin-bound loop about 1.2 metres wide winding through a small area of lawn, its curves gentle and its gradient almost flat, surfaced in a soft warm terracotta tone. Detail the circuit as a tiny piece of streetscape: a painted centre line, two miniature zebra crossings, a small roundabout with a planted centre, a scaled-down traffic light on a short post, and a couple of low road signs at child height — teaching road behaviour as much as riding. Show a start-finish arch of bent steel tube, no more than 1.8 metres tall. Detail the surroundings with a low timber edge separating circuit from grass, a bench under a tree where parents sit, and a rack of small helmets and balance bikes. Include several toddlers riding and one pushing a bike. Show soft morning light with long gentle shadows. Photorealistic, small-scale, warm and friendly, slightly elevated eye-level view.
