 # SECTION 2: PRE-FLIGHT CHECKS & SYSTEM VALIDATION
 # ==============================================================================
-#
-# Runs comprehensive system checks BEFORE container creation to catch common
-# issues early. This prevents users from going through the entire configuration
-# menu only to have creation fail due to a system-level problem.
-#
-# Checks performed (via run_preflight):
-#   - Kernel: keyring limits (maxkeys/maxbytes for UID 100000)
-#   - Storage: rootdir support, vztmpl support, available space
-#   - Network: bridge availability, DNS resolution
-#   - Repos: enterprise repo subscription validation
-#   - Cluster: quorum status (if clustered)
-#   - Proxmox: LXC stack health, container ID availability
-#   - Template: download server reachability
-#
-# Design:
-#   - All checks run and results are collected (no exit on first failure)
-#   - Clear, actionable error messages with suggested fixes
-#   - Reports "aborted" status to telemetry (not "failed")
-#   - Uses existing exit codes for consistency with error_handler/api.func
