  📝 LEARNING NOTE
  ============================================================
  Notice how every page on this site looks consistent?
  That's because they all share THIS file.

  If you want to:
  - Change the red color   → edit --color-red
  - Change the font        → edit --font-body or --font-display
  - Change card spacing    → edit the .card padding

  One change here = updates everywhere. That's the power of CSS!
