Generate an SVG as a universal occasion greeting card illustration. Festive celebratory style. Background fill #FFFBF0. Draw a warm confetti shower falling across the full canvas — confetti shapes (squares, circles, stars, triangles) in amber (#F59E0B), coral (#F97316), sage green (#65A30D), sky blue (#38BDF8), lavender (#C084FC) — avoiding hot pink or overly festive red to remain emotionally neutral. Add 3 ribbon curl shapes in amber and coral arcing across canvas. Joyful but warm and gentle. No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a white background with colorful confetti and streamers, creating a festive atmosphere. The confetti is in a variety of colors, including red, orange, yellow, green, blue, and purple, and is scattered across the surface.
