// Settings > Flatpak / Snap — the QML port of crates/qbz-ui/ui/settings/
// SandboxSettings.slint: the one-time permission commands a sandboxed
// install needs. Shown only when the process IS sandboxed
// (settings_qt/devtools.rs detects /.flatpak-info and $SNAP, the Slint's
// SandboxState.install-method).
//
// Commands are plain strings (never translated); the copy uses a hidden
// TextEdit's own clipboard (QML has no clipboard API of its own, and this
// port has no clipboard invokable to reuse).
