/**
 * Page-scoped data provider for mention avatars.
 *
 * Products inject their resolution strategy so this package remains independent
 * of Jira and Confluence APIs. Reuse the instance for the lifetime of a renderer
 * or editor rather than creating one for every mention.
 *
 * Deterministic products can supply `resolveMentionNodeData` to return an
 * SSR-safe avatar URL synchronously. It must return the same value on the server
 * and the client's first render to preserve hydration parity.
 *
 * Network-backed products supply `fetchMentionNodeData`. Calls made in the same
 * microtask are combined and account IDs are deduplicated before the fetcher is
 * invoked. A Relay adapter can query `users(accountIds:)`, then map each user's
 * `picture` and app type to a `MentionNodeData` record keyed by account ID. The
 * resolved result is cached by the underlying `NodeDataProvider`.
