/* ═══════════════════════════════════════════════════════════
   ENTERPRISE CSS — MATHEMATICALLY PERFECT RADIAL DIAGRAM
   ═══════════════════════════════════════════════════════════
   Architecture:
   • Heading and Diagram are SEPARATE layout regions
   • Diagram uses a SQUARE container (aspect-ratio: 1/1)
   • All nodes positioned via direct left/top percentages
   • SVG lines share the same coordinate math
   • ONE center, ONE radius, 8 equal angles, perfect symmetry
