# Docker-based CI for pull requests.
#
# Builds the project inside the osapp-build Docker image and runs
# CTest.  The Docker image layers are cached via the GitHub Actions cache
# backend so the slow Qt/SDK bake step is only repeated when the Dockerfile
# changes.
#
# Runs on: pull_request to master or develop (non-draft only)
