Art style: аниме 90.
90年代赛璐璐动画风格。少年主角骑在改装机车上，猛地拧动油门。后轮在地面上摩擦出白色的烟雾，火星四溅。他的表情变得狂热而专注，风吹乱了他的头发。背景的贫民窟景象开始拉长、模糊，形成速度感极强的线条。

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "аниме 90" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "аниме 90".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "аниме 90" idiom, not in any other medium.
Character appearance reference (MUST match exactly):
- 主角（少年时期）: Strong rule: style --- аниме 90 ---. 90年代赛璐璐动画风格。一个15岁的少年，身材瘦削，穿着一件洗得发白的旧T恤，手臂上有擦伤。他的眼神锐利而叛逆，在阴暗的违章建筑区背景下显得格外明亮。他正在摆弄废旧的机械零件，手上沾满黑色的机油碳垢。背景是新北三重的铁皮屋，阴雨连绵，色彩灰暗压抑。
