/* ============================================================
   CHINYERE JOHN-NNAH — Portfolio Stylesheet (refined)
   Direction: same purple/dark soul, sharper craft.
   - Better type hierarchy (Syne for display, Inter for body)
   - More breathing room (8pt rhythm, generous line-height)
   - Signature SVG accents instead of glow-everything
   - Asymmetric layout details for personality
   ============================================================ */
