前后对比图

Design a clean before-and-after comparison image built as two clearly divided panels of equal size, split by an elegant vertical center divider. Place the before state in the left panel and the after state in the right panel, keeping the subject, framing, scale, angle, and camera distance identical between the two sides so the only visible difference is the transformation itself, with the left showing the starting condition and the right showing the improved result. Label each side with a small, clear caption, and if the user provides metrics or result data, present them in a tidy row or small grid beneath or between the panels with clean type. Render any text the user supplies, including the before and after captions, percentages, or data points, exactly as written, correctly spelled; never invent statistics, claims, or filler wording, and leave data areas clean if no numbers are given rather than adding placeholder text. Keep lighting consistent and honest across both panels so the comparison reads as credible rather than exaggerated, and add a small product thumbnail if it belongs. Use a clean, professional layout with aligned margins and balanced negative space. Do not add watermarks or clutter. The result should look like a trustworthy campaign comparison. Use the details below for the subject and the exact before and after states.
