後台鏡前自拍分析

A highly structured JSON prompt for Nano Banana Pro designed to generate a realistic, candid, backstage mirror selfie. The prompt includes extensive metadata, composition rules, a detailed color profile analysis, specific lighting parameters (hard light, high contrast, vanity lights), technical specs (digital noise, deep DOF), and artistic elements (K-pop idol aesthetic, Y2K fashion).
