# Debian based image for the flash card checks (ADR-0005).
#
# Build (from the repository root):
#   docker build -f docker/debian.Dockerfile -t flash-card-debian .
# Run the linters and the tests on a virtual desktop:
#   docker run --rm -v "$PWD:/app" flash-card-debian
#
# The base image is the official Python image (Debian bookworm), because the
# program needs Python 3.13. The desktop is a virtual X screen (Xvfb) with
# GNOME Shell when it can start in a container, else GNOME's window manager.
