Optional ReadonlyauthorOptional ReadonlycarouselThe carousel's children from the grid answer; absent on a media that is no carousel.
Optional ReadonlydashOptional ReadonlyfollowsReadonlymediaReadonlypositionReadonlystartingThe starting_clips_media_id the item's like carries: the pk of the clip
the contextual feed was entered from, the feed's own fact
(host.facts.firstMediaId). The app carries the field on the button
like of the entered item itself, where the entry clip and the liked item
are one media, so choosing the entry clip for a later item rests on the
field's name, not on the app's behavior; the double-tap like carries no
such field and is not modelled.

Optional Readonlyvideo
What playing a video needs beside the address: the facts the view telemetry reports.
