### Full prompt
```text
Enhance and upscale the reference photo while strictly preserving the original composition, colors, and lighting tone. Eliminate all blur and noise. Render realistic, highly detailed skin texture with visible pores, subtle fine lines, faint freckles, and natural shadow-to-highlight gradations. Keep the facial identity and original features exactly the same.
