   Kept in its own file so the template's style.css stays pristine.

   The template's own project card (.case-block) hides everything behind a
   hover overlay. That is wrong for this page: the point is to show the
   software, and a hover overlay shows nothing on a phone and nothing at a
   glance on desktop. These cards are always readable, image on top, detail
   below, so a visitor scanning the grid can see what each system actually is.
