# Flashcard — single-container production image.
# Runs the Express API and serves the built React frontend on PORT (default 3000).
#
# The backend is launched with tsx (TypeScript runtime) because the shared
# package is consumed as TypeScript source; this matches how the app runs in dev
# and avoids a separate compile step for the shared workspace.
