   COMPONENTS.CSS - Reusable UI Components
   ============================================================

   This file contains pre-built, reusable component classes that
   leverage tokens.css. Use these in sections to maintain visual
   consistency and reduce code duplication.

   PHILOSOPHY:
   - components.css defines the WHAT (visual appearance)
   - Section BEM styles define the WHERE (layout/positioning)

   USAGE IN SECTIONS:
   Combine component classes with section-specific BEM classes:
   <div class="card my-section__card">...</div>

   TABLE OF CONTENTS:
   1. Reset & Base
   2. Layout (Container, Section)
   3. Typography
   4. Buttons
   5. Badges
   6. Cards
   7. Section Headers
   8. Icon Boxes
   9. Grids
   10. Lists
   11. Links
   12. Form Elements
   13. Images & Media
   14. Dividers
   15. Icons (Lucide)
