import PackageDescription

// Termina — a native macOS SSH/SFTP connection manager with a Terminus-style UI.
//
// Terminal rendering is provided by SwiftTerm today. The terminal layer is kept
// behind the `TerminalSurface` protocol so a libghostty backend can be dropped in
// later (libghostty requires a full Xcode + Metal toolchain to build from source,
// which is why SwiftTerm is the shipping default).
