Convert cat photo to pixel art AI Image Prompt

Using the provided reference image, transform only the inserted cat photo into retro pixel art while keeping the overall PowerPoint dark-mode Copilot screenshot layout, interface, and composition unchanged. Preserve the same tabby cat, pose, desk setting, laptop, wall charts, books, and plant, but redraw that image as chunky low-resolution game-style pixel art with visible square pixels, simplified shading, and an 8-bit feel. Also update the visible Japanese Copilot request and response text so the request says 「ピクセルアートにしてください」 and the response explains that the cat image was changed to pixel-art style, with follow-up suggestions mentioning 3 options: 「もっとドットを荒くしたい（8bit風）」, 「背景を単色にしたい」, and 「スライド右下用の小さめサイズにしたい」.
