# CollectFlow — image de production.
#
# 1. web    : compile l'interface React (Vite) en fichiers statiques.
# 2. server : compile le serveur Rust (binaire unique, optimisé).
# 3. runner : Debian minimale + Chromium (extraction Qlik) + les deux livrables.
#
# L'image est construite et publiée par GitHub Actions à chaque push sur main
# (ghcr.io/r0m1k3/collectflow:latest) ; docker-compose la tire au démarrage.
