     PERFORMANCE — content-visibility
     REMOVED for stability. The BlockDialog layout uses GSAP
     ScrollTrigger pin + CSS sticky positioning, and a long
     complex bento grid. content-visibility: auto conflicts
     with these mechanisms (pin-spacer height gets recalculated
     as 0, sticky positioning breaks, reflows visible content
     as the user scrolls). The earlier version caused
     sections to overlap/collapse.
     We retain the other major perf wins (will-change, contain,
     GPU layer hints, rAF throttling, Page Visibility API).
