    build: Make sassc mandatory
    
    Developers consistently forget updating the theme files and then when
    I get to debug theme issues I end up looking at an outdated CSS file
    that isn't even used in my theme and waste a bunch of time debugging
    non-issues.
    
    If anyone wants to make sassc optional again, they should first figure
    out a way that ensures this doesn't happen.
