//! argv handling for a `HANDLES_COMMAND_LINE` GApplication — every

|
//! invocation (including ones launched while breadhelp is already running,
|
|
//! forwarded over D-Bus to the primary instance) reaches
|
|
//! `connect_command_line`, so `--onboard` on a second launch re-triggers the
|
|
//! tour in the existing window instead of spawning a duplicate.
