template

This is the path of the template file - which matches the fully qualified classname. The templating suffix is added by the template implementation (eg. java.lang.String -> java/lang/String.hbs)

SECURITY: file-backed loaders (Caching/HotReload) pass this value straight to the engine's file resolver. Overriding this with request-derived input enables path traversal (../../etc/passwd); keep it developer-controlled.
