{"success":true,"data":{"id":"offscreen-text-in-body","label":"Off-screen text via CSS position — left/top/right/bottom: -9999px (classifier-poisoning)","description":"HTML body contains text inside an element positioned far off the visible canvas — `position: absolute` or `position: fixed` combined with a large negative coordinate (`left: -9999px`, `top: -10000px`, etc.). The text exists in the DOM and is readable by AI classifiers and keyword filters, but users never see it because it renders outside the viewport. Same attack family as hidden-text-in-body but using CSS positioning instead of display/visibility. Requires BOTH the position property AND the off-screen coordinate in the same style attribute so legitimate sticky headers (`position:sticky; top:0`) and pinned buttons don't false-fire.","tier":"danger","category":"body","isThin":false}}
