;;; lang_profile_ca.el — Catalan language profile for ELP.
;;; Mirrors lang_profile_it / _es / _pt; keys the realizer's construction switches.
;;; Catalan is the CLOSEST Romance sibling to the shared engine (~85% conceptual
;;; reuse). The deltas: PRONOMS FEBLES with four position allomorphs, l'-elision,
;;; del/al/pel contractions, the periphrastic preterite (vaig+INF), and NO
;;; essere/avere split (perfect aux is always HAVER; ser/estar is only the copula).
