#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for firewall options/ref cmdlets:
        Get-PveFirewallOptions, Set-PveFirewallOptions, Get-PveFirewallRef.

    All tests are fully offline — no live Proxmox VE target is required.
    If a cmdlet is not yet compiled the test is marked Skipped.
