Black X Symbol - Universal Icon for Error, Cancel, or Prohibition #143085 (License: Personal Use)

This minimalist black X icon features thick, slightly irregular brushstroke-style lines against a pure white background, evoking urgency and finality. Its high contrast ensures visibility across devices and accessibility standards, making it suitable for alerts, close buttons, or error indicators in digital and print media.

Commonly used in web UI (e.g., close buttons, form validation errors), signage (prohibition symbols), and graphic design to denote negation or termination; matches user intent for quick recognition of rejection or correction actions.
