How subscribers consume the observer:

• granular (default): subscribers apply the delivered ChangeMessage[] deltas to their own keyed state (Vue/Svelte/Solid). The observer subscribes with initial state and seeds late subscribers, so every subscriber converges from deltas alone.
• wholesale: subscribers treat notifications as a wake-up and re-read getSnapshot() (React/Angular). The observer subscribes WITHOUT initial state, preserving those adapters' loading policy — no snapshot request, so no unfiltered loadSubset against on-demand collections. Nothing is delivered synchronously during subscribe, which keeps useSyncExternalStore-style consumers safe by construction.
