Sell it down the street.

How this works

1. Step 1: Observe

   The HEIP script watches how input arrives (timing, rhythm, variety). No keystrokes, no biometrics.

2. Step 2: Bind to the action

   On submit, prepareAction() issues a single-use nonce tied to listing.create or message.send.

3. Step 3: Server verifies

   Our server asks /v2/verify under marketplace_standard. Only ALLOW publishes. The browser never sees a score.
