/* ===========================
   Font Configuration
   =========================== 
   
   This site uses Roslindale and Graphik fonts.
   
   ROSLINDALE: Premium serif font by DJR (David Jonathan Ross)
   - Available at: https://djr.com/roslindale or Adobe Fonts
   - Used for: Headings (elegant, distinctive serif)
   
   GRAPHIK: Premium sans-serif font by Commercial Type
   - Available at: https://commercialtype.com/catalog/graphik or Adobe Fonts  
   - Used for: Body text and UI elements (clean, modern sans-serif)
   
   Current setup uses Inter and Crimson Pro from Google Fonts as high-quality alternatives.
   To use the actual fonts, you need to:
   1. Purchase licenses or subscribe to Adobe Fonts
   2. Add font files to a /fonts directory
   3. Uncomment the @font-face declarations below
   4. Update the CSS variables to use 'Roslindale' and 'Graphik'
