   EDITING GUIDE:
   - Brand colors are in the :root block at the top. Change them here
     and they update everywhere.
   - Font family: update --font-family. If using Aileron, add your
     @font-face or @import in index.html and reference it here.
   - Screen-specific styles are labeled with comments like
     "=== SCREEN 2: CLARIFIERS ===" so you can find them quickly.
