;;; lang_profile_ro.el — Romanian language profile for ELP.
;;; Romanian is the BIG typological delta of the Romance family. The verb/clause
;;; engine and the SACRED negation contract mirror the ES/PT/IT core, but the
;;; NOMINAL system is genuinely new: a SUFFIXED definite article, preserved CASE,
;;; a NEUTER gender, and a VOCATIVE. Those flags mark where the shared engine was
;;; extended rather than reused.
