2 * FunCaptcha (Arkose Labs) solver — API-level approach.

4 * Ported and integrated from:

5 * - noahcoolboy/funcaptcha (BDA fingerprint generation, session/challenge API, crypto, api-breakers)

6 * - useragents/Funcaptcha-Audio-Solver (audio challenge flow + speech-to-text)

7 *

8 * This module does NOT require a browser. It speaks directly to the Arkose

9 * Labs API: generate BDA → get token → get challenge → solve (audio or

10 * vision). The solved token is then injected back into the page.
