图片增强 / 放大 / 变清晰：高质量放大（Lanczos 2x/4x）+ 去噪 + 锐化 + 自动对比度/饱和度，改善偏糊、偏暗、噪点多的图片。当用户说 图片放大、图片变清晰、提高清晰度、图片增强、去噪点、锐化、图片太糊了、放大到高清、提升画质、优化图片、图片调亮调色 时使用。基于 shared/scripts/img_enhance.py（Pillow+OpenCV）。注意：这是传统增强非 AI 超分，凭空生成细节请用 ai-image-gen 图生图。与 image-editing 区别：那个做缩放/裁切/水印等常规操作，本 SKILL 专做画质提升。

> ⚠<U+FE0F> **传统确定性增强，不是 AI 超分**——能改善轻中度模糊/噪点，但无法凭空造细节。
> 要 AI 超分/重绘用 **ai-image-gen**（图生图）。常规缩放/裁切/压缩/水印见 **image-editing**。
