EMBED_BASE_URL overrides the committed embedBaseUrl for a host's own tree build

Browse source 
A host that builds its own tree (maps-dev's /cdn build inherits the container env) can bake
absolute embed snippet URLs without a committed config change, the same pattern as
DOXA_SYNC_PATHS. The value is the base without the tree name; a trailing slash is trimmed.
check-embed-targets-exist reads the same effective base. Unset, the tree is byte-identical.
