# BuildArena Challenge

Role: Senior frontend product engineer.

Project: Browser Mini Operating System v1.0.0

Objective: Build a fictional browser desktop that demonstrates coherent, persistent multi-window interaction.

Required outcome: Desktop, dock or taskbar, draggable and resizable windows, minimize/maximize/close, search, notes, terminal, file explorer, settings, themes, keyboard shortcuts, and persistent window state.

Build order: Inspect the environment; build window focus and movement; prove resize/minimize/maximize/close; add useful applications; add persistence, themes, and shortcuts; run production validation.

Verification: Run package scripts and verify a multi-window workflow, state after reload, keyboard shortcuts, narrow-screen behavior, and console output.

Evidence to return: Commands, test results, interaction recording, known bugs, missing requirements, human intervention, final commit, and deployment URL only when authorized.
