// TransactionTable — what the Répartition button opens (#369).
//
// A static render never shows a window: they open on a click, through the
// table's own state. React's hooks come from the shared harness
// (src/test/hookHarness.ts, #409): the table runs as a plain function, its
// state survives from one call to the next as between two renders of a mounted
// component, and the test clicks through the props the table hands to each
// SplitButton, then renders again to read what opened.
