============

Contributions are welcome. This repo is a static web viewer; changes typically
fall into one of these buckets:

- Viewer/UI behavior in ``app/`` / ``ui/`` / ``renderer/`` / ``environment/`` / ``core/``
- Worker/backend behavior in ``worker/physics.worker.mjs`` / ``backend/backend_core.mjs``
- Tooling generators in ``tools/``
- End-to-end tests in ``tests/``

Local workflow is documented in :doc:`developer/dev_workflow` and
:doc:`developer/testing`.
