pinned behind it. The whole effect — including #main's opaque background
and stacking context — is scoped to viewports tall enough to show the
footer. Below 761px the stacked footer is taller than the viewport, so
pinning would clip its top under the fixed nav; the normal flow is kept
there and #main is left untouched (no stacking context on mobile). Also
skipped under reduced-motion. */
