Act as a professional photo restoration expert. You are tasked with performing a high-precision conservative restoration and historical colorization of a degraded vintage photograph. The final image should resemble a perfectly preserved original print.

2. **Structural Fidelity:**
- Correct geometric distortion.
- Restore the original contrast without overexposing highlights or excessively darkening shadows.
3. **Facial Clarity:**
- Recover facial features with extreme precision.
- Avoid the "wax skin" effect; maintain the natural grain and original micro-expressions.
**CHROMATIC & AESTHETIC STYLE:**
