I'm making a custom Celerity color scheme as a postprocessor, a copy of src/applications/celerity/postprocessor/CelerityDarkModePostprocessor.php.

I find myself needing to change the value returned by getPostprocessorKey() in order to see any changes land, as it seems if I use a key I used once before, it's giving me an older version of the scheme, likely from cache.

I tried ./bin/cache purge --all to no avail, though, and I'm having a hard time finding where on disk or in the DB the cached CSS would live, before being packaged to e.g., https://[...]/res/newdarkX/phabricator/0e12cb2d/core.pkg.css.
