DesignLayout now hides its 260px sidebar below lg and shows a fixed
bottom bar surfacing the current page. Tapping it opens a 50svh bottom
sheet with the full nav list (grouped, scrolls internally) plus the
back-to-site link. Route changes auto-close the sheet and the backdrop
is tap-to-dismiss.
Hero split variant: drop the grid's items-center and add lg:justify-center
on the copy column so the headline/CTA block now lines up with the
image's vertical midpoint instead of sitting at the top.
