This will mainly impact the JsonMap, there might be some unobserved behaviour with the the program trying to search through the techui-support directory and not finding the file (also dependent on the version of techui-support). But it's also easily reversible, and I'd like to see it on VISR.

if you want to test this on an ixx-services repo, you can tag the techui-builder commit as something like this:
0.7.8-beta.1
then run locally with
uvx techui-builder@0.7.8b1 <command>
