# =============================================================================
# Deploy SQLInsight Pro-webstedet (sqlinsight.seosoft.dk) til appserveren ved push til main.
#
# Samme mønster som deploy-hub.yml: runneren er host-mode, så .env og compose-filen skrives til INSTALL_DIR
# via en kortlivet helper-container, og 'docker compose up' køres i docker:cli.
#
# Påkrævede secrets: HOST_BIND COMMUNITY_PORT COMMUNITY_CONTACT
# Valgfri: TRUSTED_KEY_ID + TRUSTED_KEY (offentlig nøgle, som feedet er signeret med, hvis den ikke er indbygget)
