Videos: a tap on the picture goes full screen. The corner full-screen button is a reach on a phone, so a tap anywhere on a feed clip — outside the player's own big play button and control bar, judged from the tap's position since those live inside the video element — now goes full screen (a wide clip asks for landscape). Full screen, a tap pauses a playing clip, and a tap on a paused one (again outside its play button and controls) comes back out. A video's taps no longer reach the post either: a tap on the player's controls used to open the thread, which in full screen took the player out from under the reader. tools/video-tap-test.js
