Naming it PayDown

Halfway through planning I realized the thing didn't have a name.

Claude pitched a shortlist and three survived: ZeroDue, Burndown, and PayDown.

I picked PayDown because it's literally what the app does. You pay down debt; the app shows the date you're done. Nothing to explain in an App Store listing.

Burndown didn't lose entirely — it became the brand mark. The icon is a burndown chart line heading to zero, which is exactly the chart the app draws for your balances.
