   SECTIONS — Homepage Section Variations
   
   Four distinct section patterns for homepage content blocks:
   - Section 0: Latest (recent articles grid with header)
   - Section 1: Categories (category showcase with images)
   - Section 2: Featured (single featured article highlight)
   - Section 3: CTA (call-to-action conversion block)
   
   Each section is designed to guide users through the homepage.
