  - .section-padding-sm  = 60px  (Compact areas, transitions)
  
  Content Width Patterns:
  All sections use proper Bootstrap structure: container → row → col-*
  
  Wide sections (Hero, Events, Footer):
    .container > .row > .col-12.col-lg-9
    → 100% on mobile/tablet, 75% on large screens (900px of 1200px)
  
  Standard sections (Problem, About):
    .container > .row > .col-12.col-md-10.col-lg-8
    → 100% on mobile, 83% on medium (800px of 960px), 66% on large (800px of 1200px)
    → Narrower for better readability of body text
