Architecture
MVVM with SwiftUI views backed by AppKit via NSViewRepresentable. The editor core uses the native NSTextStorage/NSLayoutManager/NSTextContainer stack. Syntax highlighting runs asynchronously on a background queue with generation tokens to prevent stale results. Git operations run in parallel via GCD. Project-wide search uses Swift concurrency with sliding-window parallelism.
