/* ---------- 10. Split feature blocks -------------------------------------
   MEDIA SHAPE — the panels are square and the artwork fills them corner to
   corner. Every source image is already 1:1 (sqi_logo_main and Neurodesy_Logo
   are 1254 square, mpfacemesh is 3277 square), so `object-fit: cover` inside
   a 1:1 box fills completely without cropping anything away.

   Width comes from the grid column and height follows from `aspect-ratio`,
   so the panel rescales continuously with the viewport — no fixed pixel cap,
   no media query, no JS. That is what makes it behave on phones, where the
   columns collapse to one and the square goes full-bleed.

   This is the "fixed-size floating panel" branch the previous note described:
   `align-items: center` plus `aspect-ratio` on .split__media, replacing the
   old stretch-to-the-text-column behaviour and its --media-min-h floor.
