/* The GreenGuard art is a transparent cut-out, so it carries its own white
   rounded mat here -- otherwise the unit floats naked on the navy backdrop.
   width:auto is load-bearing: build.py stamps width/height attributes on
   every <img>, and a max-height-only box would stretch the art sideways.
   The cap is 520px rather than 420px: the art is a tall portrait crop (0.86)
   that fills only 86% of its own frame, so a 420px box rendered the unit just
   312px wide inside a ~620px column -- visually half-empty. 520px brings it to
   about 387px without the mat outgrowing the two-line heading beside it. */
