# This postprocessor rewrites `//sourceMappingURL=` comments to include the hashed filename of the map.
# As a side effect, the default implementation also replaces relative sourcemap URLs with absolute URLs, including the CDN domain.
# We want to preserve the relative nature of the URLs, so that compiled JS is portable across sites with differing CDN configurations.
