Background thread pulls load/unload jobs from an inbox channel, invokes a caller-supplied Func<uint, LoadedLandblock?> (production wraps LandblockLoader.Load, tests inject a fake), and posts results to an outbox channel the render thread drains. Graceful shutdown via CancellationToken; failed loads reported rather than retried. 4 new tests, all green. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
