/* ==========================================================================
   Evaluating Gateways — AI Gateway page.
   A 2-column layout: Sticky title on the left, a 10-question checklist on
   the right. Placed after the dark Rollout Guide section, this section uses
   a warm light background (#f7f6f2) to transition back to the page's baseline.
   Primary blue gradient is applied to the question numbers and kicker.
   Motion: scroll-reveal rise + stagger for list items.
