Art style: аниме 90.
90年代赛璐璐动画风格。少年主角站在铁皮屋的屋顶上，俯瞰着下方密密麻麻、死气沉沉的贫民区。天空是厚重的铅灰色，仿佛要压下来。他紧紧抓着自己的胸口，表现出呼吸困难的样子。画面构图极具压迫感，色彩单调灰暗。

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。
