showPauseAd

Show a full-screen pause ad over the (paused) content, fading it in. The orchestrator's com.dolby.optiview.ads.core.PauseAdController decides when this is called; the renderer resolves the image source (static URL or vast CompanionAds), fires any creativeView impressions, and draws the overlay with a resume affordance. Default no-op so non-overlay renderers/fakes need not override. com.dolby.optiview.ads.core.PauseAdResolution carries the break, image asset, and source.
