/* TIGHTER THAN THE SCREENSHOT, ON PURPOSE (2026-08-17). The owner: *"the cropping of
   (each) screenshots has some extra on top/bottom. I think it needs further zoom to get
   rid of those areas."* A 2556-tall frame with `contain` shows the whole capture -- status
   bar, and the dead cream the app leaves above and below the model. Shortening the FRAME
   and switching to `cover` crops that away symmetrically, with no image files touched and
   nothing to re-export when a screenshot is retaken. 2330 is ~9% off, half at each end:
   enough to lose the status bar and the worst of the padding, not enough to clip the
   toolbar the shot is there to show. */
/* BIASED TOWARDS THE TOP, not centred (2026-08-17, second pass). A symmetric crop left a
   sliver of the status bar above the title bar -- the owner: *"there are still some
   'cluttering' on iPhone top-edge cropping. needs few px more."* With `cover`, the Y in
   `object-position` decides how the overflow is SPLIT: 50% takes equal bites off both ends,
   65% takes about two thirds off the top. At 2280 the overflow is 276 px, so this removes
   ~180 px from the top -- past the status bar, stopping just above the title -- and ~96 px
   from the bottom, which the dock can spare. */
