A naive flat poster system with a full sky-blue field, a rough house-shaped white inset, giant uneven black hand-lettering reading a short original headline, small badge labels, and simple thick-outlined cartoon home-life scenes drawn like marker doodles. The scene shows a main original cartoon subject or small group engaged in a simple domestic action like a pause, ritual, workshop, exchange, game, or frozen gesture. A large household prop, craft object, food item, plant, lamp, book, laundry basket, tool, speaker, cushion, or table object is present. The location is a home interior zone like a balcony, kitchen corner, doorway, studio nook, laundry room, reading corner, or living-room floor. Background elements include simple shelf objects, sofa blocks, rug grid, pendant lamp, potted plant, window, pet silhouette, wall marks, tiny labels, and house-outline details. A red capsule badge, slanted date mark, small arrow, hash mark, tiny sparkle, underline, or speech tick serves as an accent symbol. Characters wear flat casual home clothes like slippers, apron, loose shirt, pajama-like outfit, socks, or simple color-blocked clothing. Style fidelity anchors: sky-blue outer field, irregular white house inset, thick black marker outlines, giant naive hand-lettering, red capsule accent, flat poster color, simplified domestic props, chunky pink cartoon anatomy, visible wobbly lines, playful home-event layout. Do not recreate the original no-going-out life festival title, Fun at home text, 2023.12.1-12.3 date, red holiday badge, Xiaohongshu watermark, exact sofa lounging scene, black cat on couch, two original human characters, raised feet pose, phone-reading pose, shelf arrangement, house silhouette, or bottom hashtag wording. --ar 9:16
