/* No object-fit: cropping the top would cut a straight line across the ridge.
   Instead the image is scaled and slid so the ridge lands near 63% of the height
   at every aspect ratio.
     - wide viewports: width 100%, and `bottom` pushes the image down;
     - tall viewports (phones, tablets in portrait): `bottom` clamps to 0 and the
       width grows with the height instead, so the ridge and the villas on the
       left stay in frame rather than leaving a screen of nothing but sky.
   109dvh keeps the ridge at ~63%: h = 109dvh / 1.7768 (the image's aspect), and
   the ridge sits 39.6% down the image at x=0. Overflow is clipped by .stage. */
