/* Slim WG21 banner — shared by the mailing (eval) and pragma sites.

   Self-contained on purpose: it defines its own colors and fonts so it
   renders identically regardless of the host page's theme (mailing is
   dark, pragma is a light terminal look). It mirrors the landing-page
   banner, minus the WG21.org H1 and the meta row, at a reduced height.
   Reference: export/Alt Banner.png.

   Content width is kept in lockstep with the page content column: the same
   1280px max-width (--page-max on the mailing pages) and the same 0.75rem
   gutter, so the emblem, text, and building artwork line up with the
   content below the banner. */
