/* The window is a fixed landscape crop, not the whole screenshot — a full-page
   shot is 1400x1750 and shrinking all of it to fit makes the site unreadable.
   object-fit: cover + object-position: top pins it to the top of the page,
   which is the part worth showing.

   aspect-ratio also means the box has its final height before any image or
   embed arrives, so there is no layout shift in either mode.

   Ratios come straight from the mockups: split hero 640x400, centred 820x460,
   editorial 1110x520, feature row 640x320, phone 250x480. Order matters — the
