Lab: the cargo-desk study

A fourth piece joins the Lab. LAB-04 rebuilds a legacy cargo-office admin panel — the software genre that still runs parcel desks on the UK ↔ Bulgaria corridor — as one markup tree wearing two skins, with a live toggle between the faithful classic UI and a modern dark rework. Every name, email and number in it is invented demo data; it is a self-initiated study of the category, not client software.
