//
// What's included:
// - Audio CAPTCHA (Whisper, runs locally; English)
// - Text/OCR CAPTCHA (Tesseract.js, runs locally)
// - Math CAPTCHA (safe expression eval)
// - reCAPTCHA v2 (full audio-fallback flow)
// - Cloudflare Turnstile (stealth click + human mouse path)
// - Cookie jar (skip re-solving by reusing CF clearance per origin)
//
// What is NOT included (and why):
// - hCaptcha image grid / reCAPTCHA v2 image challenge / CF Turnstile
// image challenge — these need a trained CV classifier. There is no
// accurate, license-free, sub-1GB classifier for "select all cars/buses
// /traffic lights" tasks. To avoid pretending otherwise, those modes
// return false instead of guessing.
