A clean dark-mode AI chat interface tutorial mockup showing the underwater photo from the reference photo being upscaled. Exclude all external app chrome, side panels, and window details from the reference photo, using only the underwater image content. - Layout: Exactly two rounded-corner image previews of the underwater photo within the chat feed. One smaller uploaded-image preview near the upper right, and one larger generated-result preview below it, slightly left of center. Maintain the face-obscuring gray blur on the person in both previews. - Chat Elements: One user message bubble beside the upper preview containing the text "[将图片专为4K分辨率]". An assistant message label reading "显示思路" with a small blue sparkle icon and a dropdown chevron. A small rounded "来源" button placed directly beneath the larger image preview. - Callout: A download icon on the top-right corner of the larger preview, circled with a single red outline. One thick red arrow pointing from the right toward the circled download icon. - Bottom Input Bar: A dark rounded message input bar at the bottom with placeholder text "描述你的图片", attachment icons, a "制作图片" pill button, a "[Pro]" model dropdown, and a microphone icon. - Style: Sleek modern AI chat interface dark theme, deep black background, subtle neutral gray UI elements, rounded corners, clean 16:9 screenshot composition.
