사이버폭력 예방 포스터

A public awareness poster about preventing cyberbullying. A smartphone is surrounded by sharp harmful message shapes while a luminous protective shield blocks them; a supportive hand and safe reporting symbol guide the eye. Serious but empowering, organized information zones, bold hierarchy, modern Korean campaign design, teal and coral palette, no real platform logos, no graphic violence, no watermark, avoid illegible paragraphs.
