# RunPod Serverless worker: SDXL inpainting (Magic Eraser / Generative Fill / Outpaint).
# CUDA 12.1 base + torch cu121 — the same base the detect/upscale workers use, which
# runs on RunPod's RTX 3090/4090 (driver 550) hosts (12.1 <= 12.4, backward-compatible).
# Build context = repo root, so COPY paths are workers/inpaint/*.
