+"""Rewrite zh-page asset references to share the root site trees.
+
+Background: babelquarto renders the zh pass into _site/zh/ and copies the
+shared site_libs/ and images/ trees into _site/zh/ as byte-identical
+duplicates of the root copies (_site/site_libs/, _site/images/), roughly
+94 MB per deploy.  This script rewrites every zh HTML reference that
+resolves under zh/site_libs/ or zh/images/ to the root-tree equivalent,
+so both zh duplicate trees can be deleted afterwards.
+
+Only references whose root-tree target exists are rewritten; anything
+else is left untouched and reported.  Run BEFORE deleting the duplicate
+trees (deletion is done by prune-zh-duplicates.sh).
