Re-route simulator

One input. Two routings, side-by-side.

Pick a seeded origin → destination pair, set weight and commodity, and the simulator returns the primary direct routing alongside one alternative (a hub-and-feeder re-route), with per-leg kgCO₂e from the same DEFRA 2024 factors the live shipment report cites.

Simulator inputs
Origin, destination, weight, commodity — runs the curated re-route against the seeded emission factors and a deterministic cost / ETA policy.
Airport IATA — e.g. PVG
Airport IATA — e.g. ANC

Pick a lane, see both routings side-by-side.

The simulator draws per-leg kgCO₂e from the same EMISSION_FACTORS the live shipment report reads; ETA and cost are deterministic policy estimates you can audit in src/lib/reroute.ts.
