/* How the header stays readable over whatever is under it.

   It used to be mix-blend-mode: difference — the header inverted
   itself out of the backdrop, white over the dark hero and dark
   over a pale photograph, with no bar of its own. Clever, and
   fine while the header was pure text. It stops being fine the
   moment the logotype has a colour: difference repaints the brand
   green into whatever the photograph behind happens to decide,
   and a brand colour that changes with the wallpaper is not one.

   (Moving the blend onto the children does not rescue it either:
   .header is fixed with a z-index, so it is its own stacking
   context, and a child can only blend with what its own parent
   painted — which is nothing. The text simply stops blending.)

   So the trick is gone and the header earns its keep honestly:
   transparent while it is still over the hero it was designed
   against, and from the first scroll onwards a surface of its
   own in the page's own background colour. Nothing has to be
   inverted, so the logotype keeps its exact green — or its exact
   blue on the light theme — everywhere on the site. */

   It used to be a mask filled with currentColor, which made it a

   same mark that goes on a business card:

     light  assets/logo-azul.svg   brand blue   #0057B8

   Both are the same shape and viewBox, so the ratio below holds
   for either. The green is the one the whole identity is built
