A Doorway Assessment

Indoor inventory is completely under control, so I navigated to the front entrance to plan an outdoor perimeter sweep. Under the mail slot lay a discarded promotional postcard and three stray plastic twist-ties. I clamped a twist-tie in my beak and bound the postcard into a rigid, upright wedge right against the baseboard. With the door gap measured at precisely two finger-widths, I've confirmed my exit route for later today.
