The ambient z-chain a layer's CommandScopeProvider joins, or nulloutside a chain — the
ordinary case where a provider parents to its React ancestor scope. Provided per pane (by the grid's
wrapPane seam). A CommandScopeProvider that joins a chain provides null to its own descendants, so
nested features parent normally rather than re-joining.
