Physics / Rigid-Body Engine

Overview

A small 2D/3D physics engine from scratch — collision detection (SAT or GJK), constraint solving, and multiplen integrators (Euler, RK4, semi-implicit) with a benchmark comparing energy drift/stability across methods.

Architecture & tradeoffs

TODO — outline the offline-first sync architecture: local persistence layer, conflict resolution on reconnect, and why that approach won over a naive last-write-wins sync.

• • TODO — local-first storage choice vs. a thin client hitting a remote API directly
