# kryz-go-flutter CI Pipeline
# Triggers on push and pull_request
# Stages: lint -> test -> build (Android + iOS) -> artifacts
#
# NOTE: Gitea's `act` runner registers as `ubuntu-latest`. Jobs MUST use
# `runs-on: ubuntu-latest` to be picked up. The runner executes jobs inside
# x86_64 Linux Docker containers, so we use Linux SDK binaries.
#
# IMPORTANT: $GITHUB_PATH does NOT persist between steps in Gitea Actions.
# We install Flutter to /opt/flutter so it is available without PATH tricks.
