Description: Reports and plots the conditional effect of each variable
        involved in a multiplicative interaction across the range of
        its moderators, together with the region over which that effect
        is distinguishable from zero. Extends the classic framework of
        Johnson and Neyman (1936) and Johnson and Fay (1950)
        <doi:10.1007/BF02288864> to three-way interactions and to
        Bayesian models. The single entry point JN() dispatches on the
        fitted object, with methods for lm()/glm() models, 'lme4'
        models, 'RSiena' and 'multiSiena' results, and matrices of
        posterior draws; support for further model classes is added by
        writing one jn_input() method. Results are classed objects with
        print(), summary() and plot() methods, and the figures carry
        data-density panels showing how much empirical support each
        part of the moderator range has. A detailed introduction can be
        found in Krause (2026) <doi:10.48550/arXiv.2604.22051>.
