I took your suggestion and included the Fordson variables and basic styling from scss_lib.php and now we can upload and use the default Bootswatches and specifically I used the ones from Bas.
This should open up a bit of freedom for those wanting to change up the look of Fordson beyond what the color choosers would allow.
Thank you guys so much for all the help and tips to get things working!
I still have a bunch to do but this will set up a new for people being able to download and use Bootswatches with Fordson. I really think that beyond just the default presets I will design just for Fordson that end users will love that things will be compatible with core presets.
