\begin{minipage}{0.95\textwidth}\vspace{2pt}\footnotesize\textit{Notes:} $V$ = Cramér's $V$ of the region $\times$ category table of listing weights (L = one per listing; M = merchant-equal, each store sums to one; T = listings after dropping the 1\% largest stores; `stores' = count of stores present in the category). Null = 2\,000 permutations of region labels across stores (each region keeps its number of stores, each store keeps its catalogue); $p$ is one-sided. Last column: number of the $R\times C$ cells whose store-bootstrap 95\% interval for RAA lies entirely above / below 1. Variants from the preregistered robustness list (1\,000 permutations).\end{minipage}
