Street
The landing street sort, taken from the Know your grade film. 32 homes pop in, get graded and sort themselves into an A–G histogram; yours is ringed and a route shows the climb to B. It holds, glides back into the street and sorts again, looping only while on screen. The server renders the graded street, so it fails visible.
Loops while on screen, pauses when scrolled away
Static — what renders if the observer never fires
