Figma

Build me a single-player vector canvas editor, a weekend sketch of Figma's core canvas. Requirements: - A canvas editor with rectangles, ellipses, text, and frames; select, move, and resize with handles; fill, stroke, and corner-radius controls in a right panel. - A layers list with drag-reorder. - Export the current selection as SVG and PNG. - Local-first: documents persist to IndexedDB, with import and export as JSON. - Vanilla JS or Svelte on a single canvas element, pick the simpler to ship; no backend at all. - No accounts, no telemetry, everything stays in the browser on my machine. - Out of scope: multiplayer, comments, components, auto-layout, and plugins. Do not build any collaboration or sync layer. - README: state that this is not a Figma replacement, the moat is real-time multiplayer plus the network of people already on it, and point to Penpot or Excalidraw for serious single-player use.
