`screen-transitions.md` cites `fade_quads.py` as the command behind its decoded fade ramp, and the command had been dead since the monorepo migration: it read regn_decode.py from /work/Syplheed-Reborn and defaulted its pak to /work/sylph_extract, neither of which exists. Resolve the helper beside the script and default the pak under $SYLPHEED_DISC, the way run-canary and sylpheed-cli already do. A cited command that no longer runs is a citation nobody can check.
