📝 Walkthrough

Walkthrough

The PR adds a new module with two Comfy nodes for Quiver SVG generation. The first node converts text prompts to SVG via optional reference images and instructions. The second node converts images to SVG with an auto-crop option. Both nodes accept model and seed parameters, validate inputs, handle image uploads, and call Quiver proxy endpoints to generate SVGs. The responses are converted to in-memory SVG byte streams. An extension class registers both nodes and is exposed through a comfy entrypoint.
