Energy supply emergency declarations and contingency frameworks

Governments declaring national energy emergencies or activating contingency procurement frameworks in response to supply disruptions — Strait of Hormuz closures, pipeline cut-offs, sanctions-driven import constraints, or extreme price shocks. Distinct from EM resource nationalism (upstream capture) and food-security export controls — this is the demand-side / import-dependency vulnerability response pattern: emergency import authority, strategic-reserve draw-downs, fuel-subsidy activation, and procurement-rule suspension to secure supply.
