Gradient Side Sign-up

<!--
  The gradient panel paints its own dark surface, so its white text needs no
  dark: variants - it looks identical on a light or dark page. It carries real
  copy (a heading + pull-quote), so it is a section, not aria-hidden decoration,
  and it stacks ABOVE the form only on desktop; on mobile it drops below so the
  form leads.
