   --------------------------------------------------------------------------
   The on-screen keyboard shrinks the visible viewport but 100vh does not
   shrink with it, so a submit button at the foot of a tall form ends up
   below the fold precisely while the user is typing. Two fixes:
     1. dvh, which DOES track the keyboard.
     2. the submit button sticks to the bottom of the viewport, so it is on
        screen the whole way down the form.
