Develop an interactive Mandala Art Maker web application featuring a circular canvas with radial symmetry drawing capabilities. The interface should include a prominent color palette with vibrant neon options positioned at the right of the screen, alongside essential drawing tools. Incorporate various geometric shapes (circles, triangles, squares) that automatically replicate in a circular pattern while drawing. Core functionalities must include: Download PNG button for saving artwork, Clear Canvas option to start fresh, Undo/Redo buttons for easy mistake correction, and a brush size slider to adjust stroke width. The drawing mechanism should work in a circular pattern, automatically mirroring strokes across multiple axes to create symmetrical mandala designs. Ensure the tool maintains smooth performance and provides real-time feedback as users create their mandala artwork.
