"""FloodGate v1 on a Hugging Face Space: the OpenEnv server (reset, step, state, the MCP tools, the Task API and the web
UI at /web, whose Explore tab holds the 3D replay and every committed run's results) and the replay at /twin/.

The Space serves live mode (FLOOD_MODE=live): the agent commits the dams' releases block by block on forecast scenarios
that carry real 2025 NWS forecast errors. It runs on ZeroGPU hardware but never asks for a GPU; ZeroGPU wants one
decorated function, so `_noop` exists and is never called.

    python app.py            # http://127.0.0.1:7860/web/ (the Space's page), /twin/
