"""
VPS: put the ORIGINAL (Unity 6000-built) avatar bundles back, undoing vps_swap_bundles.py.

Why: the UnityPy-resaved "2021.3" copies fail in the 20250718 client for every bundle - even a
bundle that was natively 2021.3 and was merely re-saved - while the untouched originals are
byte-identical to what the reference server (cdn.recflare.net) serves and loads on PC. The
converted copies are parked in /opt/campus/conv2021/out/<name> so this is reversible.
No catalog rewrite is needed any more: the server stamps each definition with the sha256 of the
file it serves (BundleHashes), so restart the service and the hashes follow the files.
