Design a printable birthday party invitation for {{child_name}}. The theme is {{party_theme}}. Text, in this order of importance. Render the text exactly as written, spelled correctly, nothing else. 1. "{{child_name}}'s Party": the headline, big and joyful, about 3 times the size of the details 2. "{{event_date}}": second 3. "{{venue}}": third, the same size as the date 4. "RSVP" followed by a short blank line, so parents can write in a number by hand Layout: 5 x 7 in portrait. The headline runs across the top third, flush left, with one theme illustration in the middle and the details stacked at the bottom on a shared left edge. 0.375 in margins, with real empty space so it doesn't feel crowded. Type: one rounded, chunky display face for the headline and a friendly plain sans for the details. Two families at most, nothing thin. Color: three cheerful colors that suit the theme, such as tangerine #FF8C42, sky blue #4FB3D9 and sunny yellow #FFD23F, plus white and dark navy for the text. Flat color. Imagery: one theme illustration as the focal point, in a cut-paper style with simple texture, like a well-made picture book. Original designs only: no characters from shows, films or toys. Print: 5 x 7 in, 0.125 in bleed, text 0.25 in inside the trim, 300 dpi. After the image, add one line reminding me that AI images are RGB, so I should convert to CMYK and check the colors before printing. Avoid: garbled or extra words, invented dates or addresses, existing cartoon characters, glossy 3D, sparkles and glitter, purple-to-blue gradients, clip-art balloons everywhere, more than one focal point.
