Gitlab doesn't render the colors. I assume this is because it removes
the styles when sanitizing the HTML, which is sort-of reasonable
(except it could inspect them deeper and see that these are harmless).

We manually use the "File -> Plot" function because KiBot only
exports the first page (despite `all_pages: true`).

- place all components on the board without any regard to whether
  it makes sense
- generate gerbers, BOM and placement files
