   The body itself owns the base gradient — a deep magenta-violet
   vignette with a soft pink glow biased toward the top-center. Living
   on the body means it covers the viewport with no seams, ever, on any
   aspect ratio. Prefixed declarations are listed first as fallbacks for
   very old browsers; modern browsers will use the unprefixed version.
