/* The supplied artwork is a STACKED badge: 1248x914 (~1.37:1), wordmark over
   a flaming-ball graphic. Height is therefore the binding dimension — at the
   briefed 164px width it would stand 120px tall and blow through a 94px
   header. Sizing by height keeps it inside the bar and, because width is
   auto, the aspect ratio can never distort.
   (A wordmark-only variant, gleasonteniis-without-tennisball.png at 624x279
   / 2.24:1, would render 164x73 here — swap the src + these two heights if
   the wider lockup is wanted.) */
