Diapositive de Chat en Pixel Art dans PowerPoint Copilot

Using the reference photo of a PowerPoint dark-mode Copilot interface screenshot, transform only the inserted slide image into retro 8-bit pixel art while keeping the rest of the layout, UI, and composition strictly unchanged. Within the slide, redraw the [tabby cat sitting at a desk with a laptop, books, potted plant, and wall charts] in chunky, low-resolution game-style pixel art with visible square pixels and simplified shading. Update the Japanese Copilot side panel chat text: the user prompt box displays 「ピクセルアートにしてください」, followed by an AI response stating the cat image was changed to pixel art style, and three suggested follow-up prompt pills: 「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」.
