# The full port build needs assets extracted from a copyrighted ROM, which CI
# does not have. This job validates everything that does NOT depend on those
# assets: the PC-port tooling, the generated ROM-asset symbol files, and a
# CMake configure of all three regions (which checks REGION_DEFS, the source
# list, and that SDL2 / zlib / OpenGL are discoverable).
