deepfounder-ai/desigma ? reverse-engineered prompt

Build me a native desktop design app that feels like a simpler Figma alternative, but runs fully local and is written in Rust.

I want to be able to create frames, use auto layout, edit vectors and shapes, make components and variants, work with variables and modes, and wire up basic prototypes between screens. It should also support importing real Figma files, and it should be fast and offline first, with no web app or Electron stuff.

If possible, include a presentation style deck mode too, where I can make slides from editable frames, rearrange them, add speaker notes, and export slides or the whole deck to PDF. Make the UI feel familiar for designers, with common shortcuts and a clean inspector panel. If you need to, look up current docs online for any Rust or desktop app details.
