# Golden Face Ratio Analyzer

Upload or capture one clear adult face photo to estimate phi score, face score, facial symmetry, face shape, and visible proportion fit against φ ≈ 1.618.

## What phi score measures

Phi score is a 0 to 100 estimate of how closely visible facial proportions in the submitted photo appear to match common Golden Ratio references. It is a separate result and does not change the weighted face score.

## How to interpret it

Use phi score as photo-level appearance feedback, not an exact biometric, scientific, medical, identity, or beauty measurement. Camera angle, lens distance, crop, expression, lighting, and focus can change apparent proportions.

## API fields

The structured response includes `phi_score.score`, `phi_score.reference_ratio`, and `phi_score.explanation`.
