 - The monorepo uses `uv` workspaces.
 - `tox.ini` defines the test matrix - check it for available test environments.
 - Do not add `type: ignore` comments. If a type error arises, solve it properly or write a follow-up plan to address it in another PR.

 - Whenever applicable, all code changes should have tests that actually validate the changes.
