To help people understand that broadcasting is not a precise technology,
we have shown the estimate bleed area on the map.
Because people aren’t familiar with the technology a visual only clue is
not enough. So this commit adds a key to the map, which explains what
the different outlines mean.
It also removes the sticky footer from this page to:
- make the key visible on the page
- make people scroll and review the map before they get to the big green
button
- not reduce the size of the map any further
