One script installs every unit. Each is contextual — matched to the page — and behind a single viewability-gated autoplay decision, so a unit never plays into a frame no one can see. Figures are real network placements.
A responsive 16:9 player that mounts inside the article body, matched to the page it lands on.
A grid of contextual thumbnails below the article or on index rails — click-to-play by definition.
A sidebar unit that carries a click-to-play video or falls back to a house/display banner.
A full video destination on the publisher’s own domain — their brand, Relay’s catalogue and runtime.
The tag carries only a network-issued key — the server resolves the publisher and destination, never the page. A slot is a single attribute; the runtime does the rest: classify, match, decide the ad, play.
