Initial commit — ComfyUI on NVIDIA fronted by Open WebUI

Replaces the figment/segment/Forge stack with a single ComfyUI backend
fronted by Open WebUI's native ComfyUI integration. ComfyUI is built from
the official manual install for NVIDIA. Ships txt2img and img2img workflow
templates plus matching node-mapping JSONs that paste into Open WebUI's
admin panel.

+# comfyui-nvidia
+
+ComfyUI image-generation backend, NVIDIA-accelerated, fronted by Open WebUI for
+multi-user chat and image generation/editing.
+
+Built from the official ComfyUI [manual install for
+NVIDIA](https://docs.comfy.org/installation/manual_install#nvidia) — no third-
+party base image. Two services on one bridge network:
+
+| Service     | Port (host) | Role                                            |
+| ----------- | ----------- | ----------------------------------------------- |
+| `comfyui`   | `8188`      | ComfyUI server + native web UI                  |
+| `open-webui`| `3000`      | Multi-user chat with txt2img / img2img panel    |
+
+Open WebUI submits ComfyUI workflows directly via the documented integration —
+no MCP shim, no API translation layer. Workflow templates live in
+[`workflows/`](workflows/) and get pasted into Open WebUI's admin panel during
+setup.
+
+## Quick start
+
+```sh
+cp .env.example .env
+# edit .env — set OPEN_WEBUI_SECRET_KEY at minimum
+docker compose up -d --build
+```
+
+Then drop a checkpoint into the `comfyui-models` volume and finish the Open
+WebUI ComfyUI configuration. Full walkthrough in [SETUP.md](SETUP.md).
+
+## Replaces
+
+This repo supersedes the previous figment + segment + Forge stack. ComfyUI's
+node graph covers everything those services provided (txt2img, img2img,
+inpaint, mask generation via SAM/GroundingDINO custom nodes), and Open WebUI
+talks to it natively.
