/**
 * observer-queue/ — RFC-001 deferred observer delivery, Blocks 2–5.
 *
 * The pure "one beat behind" pipeline:
 *
 *   producer ─► capture (Block 1, `capture/envelope`) ─► MergedQueue
 *   (Block 3, seq-stamped over a BoundedRing, Block 2) ─► FlushDriver
 *   (Block 4, armed-once microtask checkpoints, flushBudgetMs) ─►
 *   DeferredDispatcher (Block 5, isolated listeners + inflight + stats)
 *
 * INTERNAL MODULE — deliberately NOT exported from the public footprintjs
 * barrels yet. The engine wiring + public surface land with Blocks 6–10
 * (see docs/design/rfc-001-deferred-observers.md). Zero engine imports:
 * this directory may import only `../capture/` and its own files.
