Driver
A work tool used one-handed, in a car, in the rain. Its quirks make the two moments that define a shift (starting it, and finishing a delivery) physical and unmistakable.
Go-online switch
The shift starts here, so it flips like a real switch: the thumb rides a snappy spring, going online fires a one-shot ripple, and the status line blur-swaps beneath.
Slide to deliver
The most important action of the day can't be a mis-tappable button. A deliberate drag with a fill that chases the thumb; letting go early springs everything home.
Hold to confirm delivery
The hold-to-confirm pattern from the signature gallery, retoned navy for closing out a job. A held press can't happen by accident in a moving car.
Hold for a beat · release early to back out
Pulls from the shared language
