Create an eye-catching promotional poster for Black Friday that highlights major sales, featuring bold typography with "BLACK FRIDAY" prominently displayed in a dynamic layout. The text should be in a vibrant red color, ensuring it stands out against a sleek black background. The font should be large and bold, with a modern design that conveys urgency and excitement. Incorporate gold accents around the text to enhance its appeal and create a festive atmosphere. Add a stylish black balloon to the design, positioned playfully in the corner or near the text, with a gold string that adds a touch of elegance. Below the main text, include an editable text area for unique offers, ensuring it is clearly defined and easy to modify. The background should be modern and sleek, possibly featuring subtle textures or patterns that complement the overall design. The final composition should be vibrant, modern, and enticing, effectively drawing shoppers' attention to the Black Friday sales.
