   remembered; Home and Enquire still switch. Only this page sits it out.

   This one fills the viewport, so the frame is wide on a laptop and tall on a
   phone, and a single landscape photo would be cropped to its middle third on
   a phone. services.js hands over both framings; the choice is made on screen
   shape rather than a width breakpoint, so a phone held sideways correctly
   gets the wide one.

   On a tall screen the two are layered rather than chosen between: the tall
   framing paints over the wide one, so a service that has no tall file falls
   back to its wide photograph instead of losing it. A var() fallback cannot
   do this — the variable is always set, and CSS has no way to know the file
