/* ================================================
   BEN ROHR — PERSONAL SITE
   Sacred Geometry Edition · 2025

   Design principles applied:
   — Golden Ratio (φ = 1.618) for all layout proportions
   — Fibonacci sequence (8, 13, 21, 34, 55, 89px) for spacing
   — Golden ratio type scale: each size × φ from the last
   — Profile column grid: 1fr : 1.618fr (exact φ split)
   — Background dot grid at 21px (Fibonacci) intervals
   — Sharp geometric forms — no organic rounding
