robert mnuchins 857m rothko leads sothebys 4075m auction in new york

This is an art auction event with no direct commercial mechanism affecting commodity prices, supply chains, or company margins. It is a one-time transaction in the high-end art market, which is a niche asset class with limited broader economic impact. No concrete commercial channel (input cost, supply shortage, demand spike, regulatory, fx passthrough, logistics, capex cycle, inventory destock, substitute pressure) is present. The event is specific to Sotheby's and the art market, but does not trigger any of the defined sector criteria (a)-(e) as no investment, regulation, price move, economic indicator, or M&A is reported. Therefore, relevant_sectors is empty.
