Background-removal worker — rembg / U²-Net (CPU)

Replaces the unreliable in-browser @imgly remover with a RunPod endpoint. Set its /runsync URL as RUNPOD_BG_REMOVE_URL, and turn it on with NEXT_PUBLIC_APG_RUNPOD_BG=true (without the flag the app keeps using the in-browser fallback).

Contract

{"input": {"image": "<base64>", "model_name": "u2net"?}} → {"image": "<base64 PNG, transparent background>"}.

Models: u2net (default, general), u2netp (lighter), u2net_human_seg (people), isnet-general-use (sharper edges).

RunPod setup

1. New Serverless endpoint → connect this repo → Dockerfile path workers/bg-remove/Dockerfile.
2. Any GPU is fine (it runs on CPU) — pick the cheapest. Max workers ≥ 1.
3. Optional volume to cache the ~170 MB model (U2NET_HOME → /runpod-volume/u2net).
4. Copy the …/runsync URL → Vercel RUNPOD_BG_REMOVE_URL, add NEXT_PUBLIC_APG_RUNPOD_BG=true, redeploy.
