Change something at the top and everything beneath it refreshes itself in place — no remount, no reload, no scroll lost. Change something in the middle and only what is under that moves. Each Panel counts its own re-reads, so both halves of the claim can be watched.
Open a territory, an account inside it, and a deal on that account. Then change something at the top and watch what happens underneath.
Every Panel subscribes to a Resource Key that spells out where it sits: a territory, an account inside one, a deal on that account. An invalidation published `nested` reaches every subscription strictly beneath the key it names — and nothing above it.

Type in here and leave it unsaved, then change the territory or the account. The announcement reaches this Panel and waits rather than overwriting you.
Settled.
