If a wife is the primary breadwinner, do her earnings belong to her husband?

This source-based Torah study examines the question: If a wife is the primary breadwinner, do her earnings belong to her husband? The canonical Hebrew article develops the issue through Parashat Mishpatim and the sources cited there. This localized discovery layer preserves the question and the source identity; it does not add any new halakhic, medical, legal, scientific, historical, theological, or empirical ruling or claim beyond the canonical Hebrew source.
