Common issues

The preview differs from the real component.

Check inherited font, line-height, box sizing, background, and media query effects.

The style fails an accessibility check.

Increase contrast, keep visible focus, and verify touch target size in the actual component.

How to interpret the result

Use the generated value as a design-system draft and test it in the target viewport before shipping.
