Batch image editing with identity preservation, background swaps, and spatial localization via Google Nano Banana 2.

• Supports up to 20 input images per call for consistent batch edits, with 1–4 outputs per request and locked aspect ratio/resolution for gallery consistency
• Preserves subject identity, pose, and clothing while enabling targeted edits via spatial language ("background only", "left object", "upper-right corner")
• Handles localized object removal/addition, background replacement, and text swaps within images; routes to GPT Image 2 edit for multilingual in-image text, Flux Kontext for single-reference precision edits, or Nano Banana 2 t2i for generation from scratch
• Requires RunComfy CLI (npm i -g @runcomfy/cli), a RunComfy account, and publicly-fetchable HTTPS image URLs; set RUNCOMFY_TOKEN env var for CI/container deployments
