 * Browser block storage for the libp2p-js client: blocks in IndexedDB so a refresh does not
 * re-fetch everything from the network.
 *
 * The browser may evict the whole origin under storage pressure, so the store is treated as a
 * cache that can vanish between sessions rather than as durable state. Nothing we keep here is
 * unrecoverable: every block is refetchable from the network.
 *
 * If IndexedDB is unavailable (private-mode restrictions, a disabled origin, a non-DOM worker
 * without it) we fall back to memory rather than failing PKC construction: a slower client beats
 * no client.
