Media pager: up and down go from post to post, left and right along a post's pictures. Adam: swipes and arrows up/down should go to the next post's media, left/right to the next within a post. The pager is now posts stacked top to bottom, each a row of its pictures or clips side by side — a quoted post's join the post that quotes it — with dots along the top when a post has more than one, saying how many and which. Up and down (swipe, arrows, j/k, Page) move a post at a time and land on a post where its row was left; left and right (swipe, arrows, h/l) move within the post and stop at its ends. A post's pictures all load as it comes near (those along its row too); a clip's head start goes to the next post's (where its row rests), the next along this one, and the post after next, at half; the look-ahead (the feed paging on, the media crawl) counts posts. Pictures pan sideways as well as up and down at 1×. Tests find the slide on screen by where it sits (the pager's children are posts now); feed-picture-pager walks right within a post, down past one with none, back up to where a post was left, left to its first, and a sideways swipe next to a swipe up; quote-pager walks the quoting post's row (its own picture, then the quote's).
