## Overview

Paint202620 is a Java Swing drawing application. The implemented workflow is: a user selects a drawing tool in the main window, draws by dragging on the canvas, and the canvas updates and renders the selected figure. The README also describes file operations and undo/redo as team responsibilities, but the sampled code does not show those capabilities implemented or connected; they are therefore not represented as working runtime components. The autosave manager is empty. Evidence is limited to the README and the supplied source excerpts/index.
