   TECH TO FEST — DARK THEME STYLESHEET
   ============================================
   
   HOW TO EDIT THIS FILE:
   -----------------------------------------
   1. COLORS: Edit the CSS variables in :root below 
      to change the entire color scheme instantly.
   2. FONTS: Change --font-primary and --font-heading 
      to any Google Font you prefer.
   3. SPACING: Modify --section-padding for section gaps.
   4. Each section is clearly labeled with comments.
