what is arkose funcaptcha?
a captcha-widget challenge; used by arkose-labs; mints the arkose session token (verify-token) checked server-side token; escalation: low risk: a short, easy game (or none) → elevated risk: more rounds, harder 3d puzzles → block on repeated failure. 3d-game: rotate/match a 3d object, difficulty scales with session risk; the hardest captcha to farm, so arkose rotates art frequently.
