   FIXEO CHAPTER 2 — Ce qui se passe pendant que vous parlez
   Namespace: fc2-*
   Version: fc2-v1b

   DOM position: immediately after #home (hero-post-strip)
   Merges: previous how-it-works + brain engine + why-fixeo
   into ONE coherent narrative chapter.

   Dependencies:
   - css/fixeo-brain-engine-v1.css (fbe-* engine orbital)

   Mobile strategy:
   - .fc2-orbital (fbe-arena-wrap) : desktop only, display:none ≤679px
   - .fc2-mobile-engine            : mobile only, display:none ≥680px
   - .fc2-mob-grid : 2-column CSS Grid, position:static, normal flow
   - All mobile text in normal document flow — no absolute positioning
