1.4.4 Resize Text (Level AA)
What it requires: Text can be resized up to 200% (via browser zoom, not a special tool) without losing content or functionality — nothing gets cut off, overlapped, or made unusable.
Common failure: A fixed-height product card truncates or overlaps its price and “Add to Cart” button once the browser is zoomed to 200%.
Fix it: Use relative units (rem, em, %) rather than fixed pixel heights for text containers, and test the actual page at 200% browser zoom, not just a design mockup.
