Splat Sim

Create a browser-based 3D arcade flight simulator. I need it to feature force-based aerodynamics, a spherical planet called Terra with mesh terrain, and an orbiting moon named Nox. The simulator should support space flight with RCS thrusters and weapons. Key features to include are the flight physics model (handling lift, drag, and torque), an ISA atmosphere model, and a Flight Data Recorder (FDR) that automatically collects and uploads telemetry data every 60 seconds to a `/api/fdr` endpoint. The core functionality should be built using Three.js and loaded via a single `index.html`.
