   the frame chrome, the aspect and the composition, and clips the body with a
   soft fade rather than a scrollbar: the standard product-screenshot
   treatment, and it needs no interaction.
   The fade is applied only when the mock is genuinely taller than the cap
   (js/animations.js adds .is-clipped after measuring), otherwise a mock that
   already fits gets its last row dimmed for no reason. */
