/**
 * Encoding for the opaque {@link Frontier} string.
 *
 * A Loro `Frontiers` is an array of `{ peer, counter }` pairs. Consumers store
 * one in a text column, put it in a JSON body and compare two for equality, so
 * the package hands out a *string* and never a structure — that way there is
 * one canonical form and no chance of two encodings of the same point failing
 * an `===`. Loro's own `encodeFrontiers` produces the canonical byte form
 * (sorted, deduplicated), and base64 makes it column- and JSON-safe.
