Design a celebratory social media graphic for a work anniversary in the Format. Use the Color Palette as the visual foundation, with a rich violet background, bright white typography and subtle silver accents. Place the Celebration Text prominently in the center using large, bold, highly legible sans-serif lettering with balanced spacing and strong contrast. Surround the message with energetic confetti, small sparkling stars and scattered celebratory shapes, keeping the composition lively without making the text difficult to read. Add a gentle glow behind the lettering and a refined sparkle effect for depth. Keep the layout clean, festive and mobile-friendly, with generous margins and no additional words, logos or decorative borders. Render the Celebration Text exactly as written.
Use these details:
Celebration Text: "Happy 5th Work Anniversary!"
Color Palette: "Violet, white and silver"
Format: "9:16 Instagram Story"
