Showcase, step 2:

• Spotlight on the home page: a full-width banner of the collections you're closest to
  completing — backdrop, logo, "one film away" — turning every seven seconds (pausing while
  pointed at), with dots to choose; the page's glow follows the slide. Poster rows get arrows to
  slide them along, and their cards arrive in turn.
• The release strip plays when it comes on screen: posters fly in in release order, the ones
  you own light up from grey, their ticks pop, and a ring beside the heading fills to how much of
  the set you have.
• A poster grows into the page it opens, and a spotlight's backdrop into the collection's
  banner, using the browser's view transitions (Chrome, Edge, Safari 18.2+; others just navigate).

Classic is unchanged; the spotlight and the ring are in the page but hidden there (their images
aren't fetched).
