A picture in a post opens full screen, and the paperclip is a button again.

The attach control was a .btn-sm holding a 16px icon, wedged between two
full-height buttons — a sliver to aim at on a phone. It's a 48px square the
height of the row now, with a 20px clip in it.

And tapping an image opens it full screen: the image centred on a dark
ground, tap anywhere (or Escape) to close. Posts crop images to 320px so a
feed stays a feed, which makes a photograph a thumbnail — this is where you
actually look at one.

Two details in the viewer. The page underneath stops scrolling while it's
open, and the scrollbar gutter the page keeps reserved stands down with it:
fixed positioning is sized to the viewport WITHOUT that gutter, so an
"inset: 0" backdrop leaves a pale stripe down the side of an otherwise
full-screen picture.
