Design a vibrant and playful Black Friday announcement for Facebook with the headline “Black Friday Big Deal” in bold, cartoon-like typography. The text should be large and feature a blend of neon blue, pink, and purple hues that reflect a celebratory, energetic vibe. The background should be filled with glowing neon lights in abstract shapes that create a dynamic, festive atmosphere, but not so busy as to distract from the text. Below the headline, place a simple, minimalist “Visit Us” button with a subtle border, designed in a modern, flat style, to contrast against the vibrant background. Apply neon lighting effects and a slight glow around both the text and the button, enhancing the dynamic, playful tone of the announcement while ensuring they stand out.
