// The Console panel's drive (`hook/console_edit.rs`): the log window's pinned
// tail and its scroll, the focus actions, the editing keys (submit and the
// /del ghost completion), and the build command's worker handoff. The command
// parsers themselves are tested in `editor/console.rs`, and the /add, /del,
// /snap, /dup, /floor dispatches beside the rest of the drive in `tests.rs`.
