   AVENLEO — BASE
   Reset plus the root element. Depends on tokens.css.

   The page has no background artwork. There used to be a fixed three-point
   radial mesh behind every screen; it painted a full-viewport gradient layer on
   every scroll and repaint, and it is the single most recognisable "AI product"
   flourish there is. A financial interface's background is a colour.
