/**
 * Sequence capability strategy — the single on-demand factory the vault routes
 * `vault.sequence()` through to build its atomic-CAS {@link SequenceStore}. The
 * active engine ({@link withSequence}) constructs the real store (kept out of
 * the floor bundle — the store class is reached only via the opt-in
 * `active.ts` chunk); {@link NO_SEQUENCE} throws. The vault always assembles the
 * per-call {@link SequenceStoreOptions} and delegates here, so an un-opted-in
 * caller hits `NO_SEQUENCE`'s throw at `vault.sequence()`.
 *
 * Note: `vault.sequence()` is synchronous, so the factory is a plain (sync)
 * constructor — the engine is tree-shaken by reachability (only `withSequence()`
 * pulls `active.ts`, which statically imports the store), not by a dynamic
 * import. Deferred-numbering series (`withDeferredNumbering`) are a distinct
 * capability and are NOT routed through this strategy.
