# Stance

A claim whose typography IS its calibration. The agent states a claim and a confidence 0-1; the type sets itself from it -- weight from 300 (a hunch) to 900 (a conviction), size from 1.4rem to 3rem, tracking tightening and opacity rising with confidence -- under a thin confidence rail. Optional "because" (the reason) and "unless" (what would change the agent's mind, the line most opinion cards forget). A small slider lets the reader drag the confidence and watch the claim reset, which makes the mapping legible and honest. Same integer arithmetic on the server and in the slider script.
