Can I vibecode 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.
