Unsafe Rust

There is a keyword in Rust that feels almost heretical given everything the language stands for: `unsafe`. It exists because Rust's safety guarantees, powerful as they are, are necessarily conservative — the compiler rejects some things that are actually fine, and some low-level operations (talking to hardware, calling C, building certain data structures) genuinely require capabilities the safe subset forbids. `unsafe` is the escape hatch, and understanding it — what it does, what it doesn't, and how to use it responsibly — completes the picture of how Rust achieves safety.
