   `overflow-x: clip` — NOT `overflow: hidden` — is load-bearing, which is why
   it lives here rather than inline on the element.

   Several sections carry rotated decorative stamps that would otherwise widen
   the page and produce a horizontal scrollbar, so the overflow has to be
   contained. But `overflow: hidden` on an ancestor makes that ancestor the
   scroll container for any `position: sticky` descendant, and since this
   wrapper is as tall as the document, the sticky nav had nothing left to stick
   within — it scrolled away with the page, taking the only conversion CTA with
   it. `clip` suppresses the same overflow WITHOUT establishing a scroll
   container, so the nav sticks and the page still can't scroll sideways.

   Keep this on `overflow-x` only: setting `overflow: clip` on both axes would
   also clip the sticky nav out of view once it left the wrapper's padding box. */
