  # How to add a shape
  1. Get the svg shape from figma, should be ~1400 wide, ~400 high
    and only the white->transparent mask, no colors.
  2. Run it through https://jakearchibald.github.io/svgomg/
  3. Run that through https://github.com/tigt/mini-svg-data-uri
    with something like https://npm.runkit.com/mini-svg-data-uri
  4. Wrap the output in `url("")`
  5. Give it a name and paste it into the `shapes` object below.
