Biometric Hair Arch (φ 1.618)

Biometric Hair Arch (φ 1.618) is a zero-identity-swapping cephalometric AI styling engine. It extracts 468 cranial landmarks at 60 FPS, calculates aspect-corrected Neoclassical Farkas Facial Thirds, and uses Meta Muse Spark Open (via Baseten) to prescribe mathematically balanced haircuts. Features an autonomous AI Stylist agent and an Interactive Barber Brief with millimeter zone specs, clipper guards, chair scripts, and real-time multilingual translation (ES/ZH/FR). 100% ephemeral & privacy-first.
