A 60-year-old man with chest pain at rest for 30 minutes has ECG changes consistent with NSTEMI and elevated high-sensitivity troponin. Coronary angiography shows a 90% stenosis of the proximal LAD successfully treated with a drug-eluting stent. There are no high bleeding risks. What is the recommended duration of dual antiplatelet therapy (aspirin plus a P2Y₁₂ inhibitor) after this event?
