Remove the two-card destination row and the below-hero quick-links nav
from the portal so the hero fills the viewport with nothing rendered
after it. The 5 quick links (News, Screenshots, Five on Friday,
Monthly Newsletter, About) move into the hero editor as a third
buttons element in defaultLayout(), reusing the existing buttons
element type so they stay fully editable with no schema changes.
Also drop overflow:hidden on the hero section: on mobile, 100vh can
compute smaller than window.innerHeight, and with overflow hidden the
wrapped quick-links text was getting clipped at the bottom edge.
