# Build (GitHub) — pipeline CI primaria
#
# Strategia hosting:
#   - Repo primario su Gitea (push iniziale)
#   - Push mirror automatico Gitea -> GitHub
#   - GitHub esegue TUTTA la CI (Gitea non esegue Actions)
#
# Trigger:
#   - push su main (incluso quello propagato dal mirror Gitea)
#   - PR aperte su GitHub
#   - run manuale via UI
