/* ============================================================
  PORTFOLIO STYLESHEET
  ============================================================

  HOW TO CUSTOMIZE THIS FILE:
  1. Change colors → edit the variables in :root (lines ~20-45)
  2. Change fonts  → update --font-display and --font-body,
                     and update the Google Fonts link in index.html
  3. Change spacing → edit --space-* variables
  4. The rest is organized by component — use Ctrl+F to find
     what you want to edit.
