-<#
-.SYNOPSIS
-  Builds the ERP frontend (Next.js) and packages it into a deployable zip.
-
-.DESCRIPTION
-  1. Installs dependencies (npm ci) when node_modules is missing or -CleanInstall is set
-  2. Runs `npm run build`
-  3. Copies the runtime files into dist/ and zips them
-
-  The /api/* rewrite to the backend is resolved at BUILD time (next.config.ts ->
-  routes-manifest.json), so BACKEND_ORIGIN must be correct for the target environment
-  when you build, not when you start the server.
-
-.PARAMETER BackendOrigin
-  Origin of the ERPCore backend, e.g. http://127.0.0.1:6701. Overrides BACKEND_ORIGIN
-  from the environment / .env.local for this build only.
-
-.PARAMETER CleanInstall
-  Delete node_modules and reinstall from package-lock.json.
-
-.PARAMETER NoZip
-  Build and stage the files in dist/erp-frontend but do not create the zip.
-
-.EXAMPLE
-  .\build.ps1 -BackendOrigin http://127.0.0.1:6701
