   breaking every position:sticky element inside it (their nearest scrolling
   ancestor stops being the real viewport). `clip` still clips the various

   you never stop mid-way with two sections half-visible — but stays out
   of the way of the tall scroll-scrubbed sections (word-sequence, the
   video scroll-scrub, the hizmet stack), which have no snap-align and so
   are simply never snap targets. Desktop (mouse wheel) only — on touch

   it in normal DOM order; the hero and footer have none, so this shows
   through there, same as the reference site's structure.
   `filter: blur()` is the fix for it reading as "pixelated/cheap": the sim
   itself runs at a modest internal resolution for performance, so viewed at
   native sharpness the soft color field shows hard, blocky edges. A blur
   turns that into the intended soft, glowing, high-quality look — cheap,
   GPU-composited, and it's exactly how the reference's own background reads
