	name: Flutter App

	# Flutter CI runs natively on ubuntu-latest via subosito/flutter-action — NOT inside the
	# dev container. Reason: the devcontainer is a C++/firmware/docs environment; installing
	# Flutter (~700 MB) there makes rebuilds slow and fragile in network-restricted environments.
	# The Flutter version is pinned in app/.flutter-version (single source of truth for CI and
	# local installs via FVM or manual setup).
