Sleepy Astra 4-Panel Manga

Goal: Create a soft pastel 4-panel vertical manga comic about a sleepy chibi girl meeting an AI laptop late at night.

Canvas: Tall vertical webcomic page, approximately 2:3 aspect ratio, divided into exactly 4 horizontal panels stacked from top to bottom. Each panel has rounded corners, a thin pale blue border, and small white gutters between panels.

Visual style: Kawaii Japanese chibi anime illustration, delicate watercolor/pastel shading, clean thin line art, soft lavender-blue nighttime palette, gentle cozy bedroom atmosphere, minimal background detail, no harsh shadows.

Main character: A tiny chibi girl named {argument name="character name" default="Astra"} with very long fluffy white hair, a single curled ahoge on top, pale skin, large sleepy blue eyes, and an oversized pale blue pajama dress with white cuffs and hem. She should look drowsy and cute throughout.

Setting: A simple bedroom at night with a low round wooden table, a laptop, a window with tied pale curtains, a dark blue night sky with crescent moon and stars visible outside, light gray floor and wall, and a soft blue floor cushion/pillow appearing on the right side in several panels.

Panel layout and action, exactly 4 panels:
1. Panel 1: The laptop is open on the low round table at left, screen facing forward and displaying the text {argument name="laptop screen text" default="GPT-6 Astra"}. The chibi girl stands to the right of the table with both arms raised as if just waking up or celebrating, eyes closed, mouth open. A vertical Japanese speech bubble on the right says {argument name="panel 1 speech" default="アストラが来た！"}.
2. Panel 2: The laptop is now turned so its back faces the viewer on the table at left. The girl sits sleepily on a blue cushion to the right of the table, one finger near her mouth, looking thoughtful and tired. A vertical thought/speech bubble on the right says {argument name="panel 2 speech" default="すごいこと聞こう"}.
3. Panel 3: The girl leans forward from the cushion toward the laptop, hands near the keyboard, looking at the screen with sleepy curiosity. The window with moon and stars remains behind the table. A vertical speech bubble on the right says {argument name="panel 3 speech" default="朝ごはん何にする？"}.
4. Panel 4: The girl sits cross-legged on the blue cushion at left, looking extremely sleepy with half-closed eyes. The laptop sits open on the low round table to the right, angled toward her. There are exactly 2 vertical speech bubbles: the right bubble near the laptop says 「まず寝よう」 and the left bubble near the girl says 「それはそう」.

Text count: Include exactly 5 visible text elements total: 1 laptop screen label and 4 Japanese speech bubbles across the comic. Keep the Japanese text vertical inside oval manga speech bubbles where shown.

Constraints: Keep the composition simple and uncluttered, maintain consistent character design across all 4 panels, use soft rounded shapes, preserve the cozy late-night room, avoid extra captions, logos, watermarks, sound effects, or additional characters.
