    Historically three near-copies — LegendOverlay,
    LegendLayerTreeModel and legendclasseditcommands — each resolved
    "which renderer / which rows / which swatch colour" for a layer
    and had to stay in lockstep manually. This namespace is the
    single copy both legend views and the undo commands consume, so
    the on-canvas legend, the dock tree and the edit routing cannot
    drift (§J.5 legend-from-renderer invariant).
