Common questions
What limitations apply?
WCAG 2.x: AA normal 4.5:1, AA large 3:1, AAA normal 7:1, AAA large 4.5:1. Large means at least 18pt, or bold 14pt. Passing contrast is not full accessibility compliance.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
