And if you make all board squares black, you would have the ultimate solid borders, which extend all the way to the square edge.
But if you want more solid outlines than a piece was designed to have, it would be better to make the stroke width an adjustable parameter of the Diagram Designer, just like the fill color. This is trivial to do, by doing a text replacement while the image is still SVG, before rendering it.
