The shop's website, the product catalog behind it, and the inventory screen the wheels lived on. This is what was running the year before Templatizer was written, and it is the last thing that was.
What to look at. The Inventory tab, and specifically the row of headings across the top of that grid: Item Number, Days, Location, Qty, Cost, Price, Shipping, Online, Ebay, Size, Width, Pattern, Finish, Condition, Vehicle, Status. That row is the question the whole business turns on being asked for the first time, which numbers identify a wheel and which ones sell it. Note how you got in, too. Not a username and a password: a PIN, on a screen that also says scan or enter the item number, because the person using it was standing in a warehouse.

Three tabs, one application. The first is the site the public saw. The others are the admin behind it, where the work was done.
The login is already filled in. Change something, switch back, and it is there. They share a session, exactly as they did.
