masque: Structurally Faithful Development Surrogates for Tabular Data

Turns a confidential tabular dataset - a single table, a folder of files, or a multi-sheet workbook - into a structurally faithful synthetic clone suitable for pipeline development. Experimental-design allocation and the NA pattern are preserved exactly; categorical design, treatment, and covariate vocabularies can be reversibly aliased; outcome and numeric-covariate values are re-simulated via a Gaussian copula that preserves the global covariance structure. Columns shared across tables are aliased consistently so the synthetic tables still join. A private 'recipe' object round-trips a pipeline written against the synthetic clone onto the original data. Not a differential-privacy or anonymisation tool: outputs are development surrogates, not public-release-safe artefacts.
