/**
 * SIWE-based authentication helper for OpenSea.
 *
 * Establishes a browser-style wallet session, creates a one-day scoped token,
 * and exchanges that token for the short-lived JWT used by REST and MCP. Token
 * management remains bound to the wallet session, while automatic JWT refresh
 * uses the scoped token.
 *
 * @example
 * ```ts
 * import { OpenSeaAuth } from "@opensea/sdk"
 *
 * const auth = new OpenSeaAuth()
 * const token = await auth.authenticate(signer, {
 *   scopes: ["read:eligibility", "write:orders"],
 * })
 * const freshToken = await auth.getValidToken()
 * await auth.revoke(freshToken.accessToken)
 * ```
