# Cozcade adaptation

Upstream: https://github.com/MaxBittker/sandspiel
Pinned commit: 9936e06b07a583aedfba9589c0cead2917f405fb
License: MIT

Modified 2026-10-02: Built the original MIT Rust Universe/tick/paint simulation as browser WASM using a fixed Cargo.lock, with neutral wind because the original fluid UI is omitted. Added a local Canvas interface, element picker, brush, keyboard/touch controls, pause/undo/clear and readiness after the first actual simulation frame. Omitted Firebase, community gallery, accounts, Sentry, ads, tracking, sharing and remote resources. Includes complete modified Rust, JS, WASM and build/license documentation.

Runtime graphics use original Cozcade Canvas colors; no upstream image, font or audio assets. MIT original notice, Pavel Fluid provenance notice, all 27 Rust/WASM dependency license files and Unicode-3.0 notice are included. Original fluid-renderer code is not shipped.
