   Product sims — simulated, animated app screenshots for marketing pages.
   A .psim is a window frame; a variant block inside provides the scene.
   Animations run when .is-live is set (marketing/productsims.js adds it via
   IntersectionObserver and removes it when scrolled away, so scenes replay).
