/* The red bloom, per Figma "Ellipse 21872": 500x271, #520C0C at 50%, layer
   blur 323.6. Reproduced as a real blurred ellipse rather than a radial
   gradient, because a gradient cannot match a Gaussian blur's falloff.

   BLUR VALUE IS HALVED, deliberately. Figma's layer-blur number and CSS
   blur() are not the same unit: CSS takes a standard deviation, Figma's is
   closer to a diameter, so blur(323.6px) spreads a 271px-tall ellipse until it
   is all but invisible. blur(161.8px) is the same ellipse at the density the
   mockup shows. Every other value here is the Figma number verbatim.

   Anchored bottom-right so it sits behind the contact block, as in the design.
   .gs-footer has overflow:hidden, which is what keeps the 323.6px bleed from
   spilling onto the page. pointer-events:none so it can never eat a click. */
