/* ==========================================================================
   Why a Gateway — AI Gateway page, below the hero. Editorial "why" narrative:
   left masthead title, right multi-paragraph body. Text-forward SUPPORTING
   section (the hero is the page focal), so it stays light and quiet with the
   blue primary used only as accents. Layout borrows the masthead+prose idiom
   but as a two-column essay — distinct from the single-column hero.
   Primary blue gradient #0036FA → #4E87FC on kicker + accents. Cabin type.
   Motion: scroll-reveal rise + stagger (~0.6s ease).
