Captcha validation UI

Explore the same interaction pattern used on ALTCHA-style widgets: checkbox → verify progress → success, with an optional accessible code challenge for high-risk scores. Production embeds use the real SDK; this page is the design-faithful demo.

Idle: “I'm not a robot” — checkbox affordance, brand mark “SHIELDWALL / Privacy protected”.
Verifying: “Verifying… N%” — spinner + thin progress bar (PoW progress).
Verified: “Verified” — green check, soft success wash.
Challenge: “Extra check required” — confusable-free code face + input (production adds audio).
Failed: “Try again” / inline error — never puzzle images.
