What process creates the stylesheet assets during build, e.g. `/stylesheets/color_definitions_dark_1_1_603243e2b6c0b7xydx234the00538538bd705.css`

I’m assuming this is the process of bundling?

What might be going wrong if these are missing?

Should these start to exist as part of starting ember-cli or the rails server?

What approach should I take to build these in docker from the standard discourse image or should I expect them to exist by simply launching the servers?
