## Overview

This repository is both a GitHub Copilot App learning exercise and the small bookmarks app built during it. The exercise guides learners from a session-created issue through project instructions, implementation, pull-request review and merge, browser preview, and release planning. The app’s documented runtime saves URLs as generated short slugs in browser localStorage. App source excerpts were not provided, so its internal wiring is shown only at the documented feature level.
