Build a pixel-art editor as a static web app in this directory: index.html, style.css, editor.js, palette.js. A 32x32 grid canvas with pencil/eraser/fill/eyedropper tools, color palette + custom picker, undo/redo, zoom, grid toggle, export as PNG (scaled 10x) and as JSON, import from JSON, keyboard shortcuts, dark theme, and tests.html + tests.js exercising the flood-fill and undo stack logic. Run the tests headless with node and fix what fails.
