+      "Movie and show pages are much richer: several rating sources side by side (IMDb, TMDb, audience), a facts panel (release, runtime, certificate, budget, revenue, studios, countries), tappable keyword chips that filter your library, and the full key crew — click a name to open that person’s page.",
+      "Cast and crew pages now show a biography, birth facts, and a “Known for” row of that person’s titles you have in your library.",
+      "Detail and person pages gain a slow, gently crossfading backdrop drawn from the title’s artwork. It respects a reduced-motion preference and can be switched off from the page’s customise menu.",
+      "Clearer Plex filters: type-to-search pickers for genre, age rating and a new studio filter, plus the collection filter — each shows your choices as removable chips and is fully keyboard-operable.",

+      "All the enriched data — ratings, keywords, crew, budgets, biographies and recommendations — is fetched from The Movie Database in the background and stored locally, so pages stay fast and keep working even when TMDB is unavailable.
