When a page isn’t there
Follow an old link or mistype an address and you now land on a page that still looks like Layout, with a clear way back to the homepage.
Move your pointer, or your finger, around the mark and it comes apart into a trail of squares, each one the size of the mark’s own blocks. Where the trail crosses the mark, it turns it inside out.
The copy menu also opens for everyone now, so you can see every way to take a prompt before you sign in.
