 # DesignCraft — instructions for agents
 
-DesignCraft is a clean-room, open-source, Rust-native page-layout application targeting Adobe InDesign parity — and superiority (speed, openness, agent control). It runs natively on macOS, Windows and Linux, and on the web via WASM. Siblings with the same conventions: `../drawcraft` (Illustrator-class), `../photocraft` (Photoshop), `../printcraft` (Acrobat), `../filmcraft` (Premiere), `../lightcraft` (Lightroom).
