Collapse brief.store's busy signal + nullable lastError into one Idle |
Busy | Failed union (saveState gets matching tag-object style), and route
brief.page's load through RemoteData + <app-async> instead of a hand-rolled
@switch, via a BriefStore.remoteData projection of the machine's existing
loading/failed tags -- the machine keeps owning the letter's own status
lifecycle untouched. New brief.store.spec.ts covers the Busy->Idle/Failed
transitions; new Foundations/RemoteData & Async MDX page documents the
pattern and the WP-06 typed-loaded-slot fallback. Deviation from the
original plan recorded in the WP file.
