# BuildArena Challenge

Role: Senior frontend product engineer.

Project: Minecraft-Inspired Inventory Interface v1.0.0

Objective: Build an original block-survival inventory system with dense, consistent state and no protected copied assets.

Required outcome: Inventory grid, hotbar, drag and drop, item stacks, stack splitting, tooltips, equipment slots, crafting interface, keyboard interaction, original icons, and responsive scaling.

Build order: Inspect the environment; implement stack state; prove movement and split behavior; add equipment and crafting; add keyboard behavior and responsive scaling; run production validation.

Verification: Run package scripts and verify item counts, crafting, keyboard interaction, mobile layout, 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.
