This touched a lot more code than initially expected, for two reasons. First, this broke a big RGBASM assumption: that sections are always being written to at their end. This plus other problems required touching basically the entirety of `section.c`. Second, I tried different solutions to solve the above problem, and along the way I cleaned up many things around. (I believe that keeping this to "cleanup" commits yields subpar results, and since it's boring they get postponed anyways.) RGBLINK support still needs to be added, but this will come next.
