/* The logo's wordmark is dark navy on a transparent background, which
   disappears against the header's dark navy backdrop -- a small white
   chip behind it keeps the mark legible regardless of the page's header
   color. */
/* .eq-brand is a wrapper (not the <img> itself) so the white chip's size is
   set independently of the logo's rendered size -- setting height+padding
   directly on an <img> is unreliable across browsers because "height"
   on a replaced element doesn't consistently subtract padding the way it
   does on a block box, which is what made the logo render oversized. */
