电商主图 - 高端抹茶饮品包装样机

Generate a photorealistic product packaging mockup for a {argument name="product type" default="premium matcha energy drink"} named “{argument name="brand name" default="FOCUS LEAF"}”. Scene: one sleek aluminum can on a matte stone surface with soft morning window light. Important details: minimalist Japanese-inspired design, pale green and cream palette, condensation droplets, realistic shadows. Include exact label text: “FOCUS LEAF”, “MATCHA + L-THEANINE”, “ZERO SUGAR”, “12 FL OZ”. Use case: product concept. Constraints: all text must be spelled correctly, no extra brand names, no distorted typography.
