Product Marketing - Japanese Chalkboard Cleaning Sign

Goal: Create a hand-drawn Japanese chalkboard sign advertising cleaning, with a cute, friendly, handmade storefront-board look.

Canvas: Horizontal blackboard poster in a 3:2 aspect ratio, dark matte black background with visible chalk texture, slightly cropped at the bottom as if photographed close-up.

Layout: Large title across the top in thick white chalk: 「クリーニング」. Add small decorative chalk lines, dots, swirls, and sparkle icons around the title in yellow, mint, and blue. On the left middle, place a pink speech-bubble outline containing the text 「こんな方に」 in white and 「おすすめ！」 in mint green. Beneath the bubble, draw one cute black cat mascot outlined in white chalk, winking, with round cheeks, whiskers, triangular ears, and one raised paw with pink paw pads. On the right middle, create one rectangular mint-green chalk outline information box with rounded corners. Inside it, list exactly 4 bullet points, each preceded by a pink paw-print icon: 1) 「忙しくて手が回らない…」 2) 「常に人を呼べる家にしておきたい…」 3) 「掃除が苦手 or 体力的に大変…」 4) 「普段使用しない建物など…」. Separate the bullet rows with dashed yellow divider lines. Across the lower center, add a wide curved ribbon banner in teal outline and black fill, with bold yellow chalk text: 「お任せ下さい!!」. Below the ribbon, include smaller white chalk text: 「分かってるけど後回しな場所です」 with a pink wavy underline.

Visual style: Japanese kawaii chalk art, rough hand-lettering, imperfect strokes, dusty chalk smudges, playful but readable typography, high contrast white/yellow/mint/pink on black. Use decorative sparkles, dots, corner borders, paw prints, and short emphasis marks, but keep the design organized like a professional shop sign.

Constraints: Use exactly 1 cat mascot, 1 speech bubble, 1 main information box, 4 paw-print bullet items, and 1 ribbon banner. Keep all visible text in Japanese exactly as specified. No photorealistic objects, no digital glossy effects, no watermark.
