   Layout: a white canvas with one dark, film-like hero. The product showreel
   straddles the hero's lower edge. Each use case is a text column beside a
   large rounded video whose chapters are listed as a progress list.

   Light theme only, by design (matches the reference). Every colour is a token
   below; the hero and the request banner are dark on purpose.
