# kryz-go-flutter Release Pipeline
# Triggers on version tags (v1.0.0, v1.0.1, etc.)
# Produces signed artifacts and attaches them to a Gitea Release
#
# CONTAINER IMAGE: The build-android job uses a pre-built Docker image
# (kryz-ci:latest) that includes Flutter, JDK 17, and Android SDK baked in.
# Build once on the runner host:
#   docker build -f .devcontainer/ci.Dockerfile -t kryz-ci:latest .devcontainer
