# The overall idea is to be quick, but re-use output from previous steps.
# The quickest checks is formatting, so we do that first. Next is integration, and ci. For ci we split up backend
# and frontend, because they are somewhat independent.
#
# For the backend part, we run check, clippy, and test as they build upon each other. For the frontend, we run
# check and clippy, but test as a dedicated job, as we don't have a WASM test runner. Yet, check and clippy for wasm32
# are different.
