I get this otherwise blank page with the message
Before we continue…
Press & Hold to confirm you are a human (and not a bot).
I hold down Space to fill the button with a solid color.
But when I release it before filling, it drains.
Eventually I get a checkmark.
Then the same screen with tiny red text:
Please try again.
I cannot tell the filling button has focus,
so I tab around for a bit.
Then I get back to the button and hold down Enter
Finally it fills, I get the checkmark and ellipses.
And it loads the page I wanted.
