Pharmacy Delivery Tracker

A parcel-style tracker for prescription medications. The card pairs an order header (Rx number, pharmacy, and a colour-coded status pill) with a vertical four-stage stepper — order confirmed, preparing at pharmacy, out for delivery, delivered — where completed stages show a check and a timestamp, the current stage pulses, and future stages stay muted. An ETA panel announces “Arriving by 4:30 PM” until handoff, a courier card with an initials avatar and a contact button appears only while out for delivery, and the order-items list shows the medications and delivery address. A demo “Advance status” button steps the whole machine forward and locks at delivered.

Illustrative UI only — not intended for real medical use.
