Chibi Cat Girl Sticker Pack

Goal: Create a cute digital sticker pack preview sheet for messaging apps, showing exactly 9 chibi stickers in a 3 by 3 grid on a clean white canvas. The main character is {argument name="character description" default="a white-haired anime cat girl with pale pink gradient twin-tail hair, blue eyes, white cat ears, a pink cat tail, a loose blue hoodie, black pleated skirt, yellow socks, and sneakers"}. Her sidekick is {argument name="mascot description" default="a small round navy-blue penguin wearing a matching blue hoodie, sometimes holding a tiny phone"}. Use a soft kawaii Japanese LINE-sticker style: rounded forms, pastel colors, thick clean outlines, expressive faces, small sparkles, hearts, motion lines, and hand-drawn bubble lettering. Canvas: square-ish white sticker sheet with rounded corners, no heavy background, subtle drop shadow, and small miniature sticker-sheet thumbnails stacked vertically along the right edge like a marketplace preview. Layout: exactly 9 large stickers, evenly spaced in three rows and three columns. Include these 9 sticker scenes and matching text phrases from {argument name="sticker phrases" default="おはよ〜, ありがとっ!, おつかれさま〜, OKだよ〜, ごめーん, いま行くー!, よろしくね, おやすみ〜, またね!"}: 1) top left, cheerful morning greeting: cat girl waves with one hand, penguin smiles beside her, yellow-orange handwritten text above; 2) top center, thank-you: cat girl bows with eyes closed and hands down, penguin bows too, orange text with a small heart; 3) top right, good-work/tired greeting: cat girl salutes while holding or standing near the penguin, blue text and sparkles; 4) middle left, OK confirmation: cat girl gives a big thumbs-up with a wink, penguin laughs, green text with stars; 5) middle center, apology: cat girl clasps hands apologetically with sad watery eyes, penguin bows deeply, blue text with sweat drops; 6) middle right, on-my-way action: cat girl runs energetically with flowing hair and tail, penguin runs beside her holding a phone, red-orange text and motion lines; 7) bottom left, please/nice-to-meet-you: cat girl and penguin bow politely, pink text with a small heart; 8) bottom center, good night: sleepy cat girl hugs a blue star-pattern blanket or pillow, penguin wears a blue nightcap and hoodie, purple text with crescent moon and stars; 9) bottom right, see you again: cat girl waves happily, penguin waves beside her, orange text with excitement marks. Add a small semi-transparent gray circular button labeled {argument name="edit button text" default="編集"} at the bottom-left corner and a small semi-transparent circular share/download icon at the bottom-right corner, like a mobile preview overlay. Constraints: keep the characters consistent across all 9 stickers, make the text large and hand-lettered above or near each sticker, use no photorealism, no extra characters, no extra sticker panels, and no watermark.
