function Publish-CciModuleToBlob {
<#
.SYNOPSIS
    Mirrors a built module into the tenant distribution store and updates its index.
.DESCRIPTION
    The tenant Azure Artifacts feed is the canonical publish target, but reading
    it requires an Azure DevOps org entitlement and a paid Basic licence per user
    (Stakeholder has no Artifacts access). Machine builders have neither - they
    hold Azure RBAC on the tenant store instead. This mirrors the same published
    module there so `Install-CciModule` can serve them without any Azure DevOps
    identity.
 
    Intended for the tenant publish pipeline (running under a service connection
    with Storage Blob Data Contributor) or for an operator with a temporary
    write grant.
.PARAMETER Path
    Folder containing the built module (the one holding its .psd1).
.PARAMETER Name
    Published module name, e.g. cciit.wincustpayload. Defaults to the manifest's
    base name.
.PARAMETER Version
    Version to publish under. Defaults to the manifest's ModuleVersion.
.PARAMETER Tenant
    Tenant whose distribution store to publish to. Defaults to defaultFeed.
.EXAMPLE
    Publish-CciModuleToBlob -Path .\out\stage\cciit.wincustpayload
