# ============================================================================
# Выпуск read-only Proxmox-токена для виджета Proxmox в Homepage-дашборде.
#
# Создаёт пользователя homepage@pve, роль PVEAuditor на / и privsep-токен
# homepage@pve!dashboard. Секрет пишется в КОРНЕВОЙ .env как
# DASHBOARD_PVE_API_USER / DASHBOARD_PVE_API_TOKEN_ID /
# DASHBOARD_PVE_API_TOKEN_SECRET — оттуда его читает playbooks/dashboard.yml
# через lookup('env', ...).
#
# Парный к playbooks/bootstrap-monitoring-pve-token.yml. Отдельный принципал,
# чтобы дашборд не зависел от кредов замороженного стека Prometheus.
#
# Запуск: make bootstrap-dashboard-token
