"""
Synchronize the standalone HF proxy page-feedback runtime mirror.

The authoritative generic feedback backend lives in ``_sphinx_feedback``.
The HF Space proxy is deployed as a standalone Docker context, so it carries a
byte-identical mirror of the server-only contracts/service package.  This helper
is deterministic and idempotent; CI compares the mirror against the source.
