OpenRouter universal gateway in Nebula — one node (openrouter-universal) that reaches hundreds of models (GPT, Claude, Gemini, Llama, DeepSeek, FLUX, Recraft, and more) through OpenRouter's chat-completions API. Capabilities exposed in Nebula: streaming text/chat/reasoning/coding, vision (image-in → text-out), and image generation (text → image) — the model you pick decides which. Activate when the user configures the openrouter-universal node (display name "OpenRouter"), picks/searches an OpenRouter model in the Inspector, or asks about OpenRouter in Nebula. Sourced from the official OpenRouter docs (openrouter.ai/docs) and the Nebula audit guide docs/api-guides/openrouter.md on 2026-06-04 — every node id, port, param, header, and capability boundary here is cross-checked against backend/handlers/openrouter.py, backend/routes/openrouter_proxy.py, and backend/data/node_definitions.json.
