+- **Native on macOS, Windows, Linux and FreeBSD**, and **in the browser** through WebAssembly, from the same Rust codebase. Windows builds come for x64, x86 and ARM64 (Windows on ARM, no emulation); every ARM64 change is tested on ARM64 hardware in CI.
 - **Private by design.** Documents never leave your machine. There's no account, no telemetry and no cloud processing.
 - **Engine first.** Parsing, rendering and editing live in reusable library crates. The interface is one swappable layer on top.
 - **Scriptable.** The `printcraft-cli` tool (see [Built for agents, too](#built-for-agents-too)) covers inspecting, rendering, extracting text, editing, combining, extracting pages and splitting. Robustness sweeps run on the same engine as the app.
