   Sized to match the legacy img/ASPHER.jpg strip: 1110x239 (~4.6:1),
   capped at 800px wide => ~172px tall on desktop.
   The artwork (img/ISER.jpg) sits on .rpb-media as a blurred, masked
   texture so the headline stays legible whatever the image contains -
   and the banner still reads correctly if the file is missing. */
