Childhood photo wedding invitation hand drawn collage

Generate a bright, child-like hand-drawn collage invitation screen. At first glance, a super large hand-painted symbol or theme glyph (a large '囍' character) occupies the central visual weight, looking like thick-coated crayons with grainy edges, blunt strokes, and a slight hand-shaking feel, serving as the emotional backplane of the entire screen. The main subject is a childhood photo of the couple, appearing as foreground material pasted in front of the large symbol, enclosed by an irregular thick doodle outline like a protective frame hand-drawn by a child, which partially bypasses the subject's edges and overlaps with the large glyph behind; the outline around the people should be a yellow hand-drawn frame. At the top, arrange a relaxed, rounded, slightly tilted handwritten title and a smaller subtitle. At the bottom, keep a row of more casual handwritten explanatory text, which looks like colored markers written on paper, with naturally uneven spacing but clear readability. The text includes 'Welcome to our wedding' and '欢迎参加我们的婚礼'. The background maintains a large area of high-brightness, clear and clean paper white space, with slight paper fiber and tiny colored confetti textures. A small amount of hand-drawn hearts, short lines, dots, and paper-like colorful scraps are scattered around to create a sense of celebration without overshadowing the main subject. Colors are extracted from the theme's own material, emotion, and sense of ritual, maintaining the relationship between the bright base color, vivid central structural color, warm handwritten information color, and a small amount of crisp warm and cold accent colors. The overall style should be high-brightness, saturated but clean, with clear boundaries, presenting a light, close, naive, and commemorative handmade visual, avoiding a refined commercial poster feel, dirty/old filters, and overly neat layout.
