/* Blog Post - full-width hero + 3-column layout with sticky sidebars
   =====================================================================
   Color philosophy: purple (#9C73FF) is the brand accent - use SPARINGLY
   for interactive elements (buttons, links, progress bar). Everything
   else uses neutrals (#1B1B1B, #374151, #6B7280, #8A8A8A, #D4D4D4).
   Hero tags use soft lavender (#C9A9FF) against dark backgrounds.
   CTA cards use dark buttons (#1B1B1B) not purple.

   - Line height: 1.8 - generous for sans-serif at this size
   - Max width: ~680px (60-72 chars/line) - optimal reading measure
   - Paragraph spacing: 1.5em - clear separation between ideas
   - Color: #374151 (gray-700) - softer than black, reduces eye strain
