   SECTION 2 · DEMAND SENSING — Credibility & Brand Collaboration  (v3)
   - Reduced width (max 960px)
   - Strict 16:9 aspect ratio on desktop & tablet
   - 2 logos removed (4 total, 8 with duplicate marquee set)
   - Fully mobile responsive: 16:9 frame relaxes on small screens
     so ALL content stays visible — no clipping
