#' Reference Taxonomic Dataset (taxobase)
#'
#' A pre-computed reference dataset for 52 candidate genera distributed across
#' major taxonomic groups. The data were retrieved from The Taxonomicon using
#' the package functions and are intended for examples, documentation, and
#' offline inspection of package output structures.
