The post-delete redirect used `(window.ROOT_PATH||'') + '/matches'`, but
window.ROOT_PATH was never defined, so behind the nginx /township mount it
redirected to the bare /matches — which hits the coderai front, not the township
tool → 404. The mount shim wraps fetch()/EventSource() to add the prefix but not
location.href assignments. Define window.ROOT_PATH=P in the shim so the redirect
(and any future ROOT_PATH use) resolves to /township/matches; with no prefix
(direct access) it stays unset and the bare /matches path is correct.
