## Overview

DJ Remix Pro is a native Android DJ-mixing interface prototype. The main user flow enters the app shell, browses or searches the mock track library, opens the landscape mixer, and interacts with simulated decks and recording controls; saved recordings can then be managed in the recordings screen. Separate product branches cover onboarding and permissions, learning content, settings and language, and the shared UI widgets. README documentation describes the architecture and mock behavior; feature-to-repository wiring is summarized rather than verified from sampled feature source.
