## Overview

This repository is a WordPress intranet stack. Its documented feature workflow is: administrators toggle registered flags in WordPress Admin, and theme features check those flags before enabling behavior. The README describes the theme and feature-flag plugin, but neither appears in the supplied file tree, so those components have no supported source path here. Other plugin capabilities are represented from the tree; sampled excerpts are limited and do not establish wiring between them.
