A shared VideoGet.cardButton({kind,tmdbId,libraryId,title,poster,status,source})
picks the right control (person->eye, movie->get, show->eye when airing/unknown
else get) so every surface stays consistent. Injected into person filmography
(known-for + credits), search results (titles + people), and detail-page cast +
similar/collection rails. Each renderer hydrates watched state after render;
card roots get position:relative so the button anchors; reveal on hover.
