/**
 * <HomeRollTeaserCard /> — in-place result card for the home-page cross-list
 * roll. Renders IN PLACE per PROJECT_SCOPE.md:222-223; the only navigation
 * is the user-initiated "Open list" link.
 *
 * Uses the DB `Movie` row shape (not the TMDB landing teaser shape). Titles,
 * genres, and group names are rendered as React text children only — no
 * `dangerouslySetInnerHTML`, no unescaped `title=` attributes.
