   One purchase on a 16-second loop, in the spirit of ChatGPT's shopping demo:
   the request is typed and sent (0–34%), the shops' products arrive with
   what Cheto understood (34–64%), the basket is paid in one go (64–97%).
   Every element runs its own keyframes over the same 16 s, so they stay in
   step without any script. Sizes are in --u, a hundredth of the frame's
   width (container query units), so the scene scales as one picture; a
   narrow frame gets a bigger --u and two cards instead of three. */
