Any fatal hls.js error set videoFailed permanently, so a brief 511NY feed
drop left the tile on a 60s snapshot until it was reopened. Now fatal
media/network errors get up to 3 in-place recoveries, and a tile that did
fall back retries video every 30s.

Clicking a camera's snapshot pins a 192x108 tile anchored at the camera --
the live HLS stream when the camera has one (hls.js; Safari native), else the
snapshot refreshed every 60s, falling back to the snapshot if the stream dies.
Up to 6 pins, oldest dropped. Players exist only while the DOT Cameras overlay
is on, so hiding it stops every stream.
