Subject: [PATCH] Gallery: its dev manifest fallback names the tree from the
 build config, not a literal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The one tree path compiled into any bundle. Built today it is byte-identical (sha 3d5467fd…);
built with the config renamed it reads /public/<new name>/manifest.json.
