Every pixel is computed on the CPU into a flat color buffer; no GPU rasterization is used. <a href="https://ebiten.org/">Ebiten</a> is used only to open a window, blit the finished color buffer to the screen, and handle input, so the renderer itself stays a pure software pipeline that also compiles to WebAssembly and runs in the browser.</p>
