a traditional Bengali-style Sangeet invitation card with a soft white textured background. Feature large, vibrant yellow and orange marigold flowers artistically placed around the corners and borders for a festive look. At the top center, illustrate a group of classical Indian musical instruments like tabla, sitar, harmonium, and tanpura with realistic details and slight shadowing for depth. Add a subtle swirl or cloud-like blue-green background behind the instruments to enhance contrast. Maintain a clean, artistic, and culturally rooted aesthetic that honors Bengali traditions while appearing joyful and welcoming.
