/*
 * Design Brief: Aevyra ← inspired by https://getavyra.com/
 *
 * Structure: light consulting site — split hero → accordion services →
 * numbered process → values grid → founder-style differentiation → purple CTA band
 *
 * Tokens derived from reference: white canvas, zinc typography (#18181b / #3f3f46),
 * vibrant purple accent (#6339f8), pastel service cards, Satoshi-like geometric sans.
 *
 * Layout types:
 * 1. header-minimal-sticky
 * 2. hero-split
 * 3. platform-statement
 * 4. accordion-capabilities
 * 5. process-timeline
 * 6. values-grid
 * 7. cta-band
 * 8. footer-multi-column
