Description: Synthetic control for studies with several outcomes. Each
        outcome receives its own donor weights, their dispersion around
        a common centroid is penalized, no single penalty is ever
        selected (the estimator aggregates over a penalty grid by
        leave-one-out exponential weighting), and the resulting mass
        profile reports how much pooling the data support. One call
        returns the per-outcome effects, the weights, the realized
        pooling, and whole-pipeline placebo p-values. Implements the
        estimator of Grier (2026) "Correlated Weights: Partial Pooling
        for Synthetic Control with Multiple Outcomes"
        <https://papers.ssrn.com/sol3/papers.cfm?abstract_id=7149398>,
        the common-weights corner of which is the estimator of Sun,
        Ben-Michael and Feller (2025) <doi:10.1162/rest_a_01592>. The
        compiled engine and a pure-R reference engine are certified
        against the Python engine behind the 'Stata' command 'ppsynth'.
