Generate an SVG as a holiday greeting card illustration. Festive celebratory style. Background fill #1A0A2E (deep indigo). Draw overlapping wrapped gift boxes at lower canvas — in gold (#F59E0B), crimson (#DC2626), and emerald (#059669) with contrasting ribbon bows and loops. Scatter bursting confetti shapes (circles, diamonds, five-pointed stars) across the full canvas in #F59E0B, #EC4899, #60A5FA and #FFFFFF. Add bold radiating starburst shapes at upper-left and lower-right corners in #F59E0B. Flowing ribbon streamers arc from the top corners curving downward. No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a group of colorful gift boxes with bows and ribbons on a blue background, surrounded by stars and confetti, creating a festive atmosphere.
