Vertical Pastel Lavender Lifestyle Poster

the prompt

Create a vertical pastel lifestyle poster styled as a character room-goods feature sheet. The theme is a soft, dreamy lavender jellyfish aesthetic with a Japanese cute editorial look — airy white background, pastel lilac palette, delicate handwritten-style annotations, sparkles and tiny doodles, mixing soft product photography with a magazine layout.

Feature a young woman character with a short platinum-blonde bob haircut, wearing a fluffy pale-lavender zip hoodie over a white inner top, shown from the chest up in the lower-right area, with her face obscured by a plain beige rectangle.

Layout — vertical poster on a clean white background with faint pastel doodles of stars, bubbles, tiny jellyfish, and musical notes:
- Top header area: speech bubble intro, main title, small "GOODS" subtitle, a horizontal lavender ribbon tagline, and a round badge in the top right
- Upper and middle left: a featured goods grid of 6 products:
  1. A small translucent jellyfish-shaped lamp glowing softly in pale blue-lavender
  2. A plush pastel-lavender bed with fluffy comforter and pillows in dreamy cozy styling
  3. A small tabletop mirror with a puffy shell-like pastel-lilac frame and rounded base
  4. A ceramic mug with a lavender-to-pink gradient and simple jellyfish illustration
  5. A pastel storage box holding cosmetics and bottles, decorated with a jellyfish emblem
  6. A small fluffy cloud-like jellyfish mat in pale lavender and white
- Upper right: a handwritten side note: "Everyone, come hang out and chill in Jellyfish-chan's Room with me"
- Lower left: a room concept box labeled "Jellyfish-chan's room-decor obsessions" with 3 concept points: (1) Colors unified in white and lavender, (2) A fluffy space where light gathers, (3) Surrounded by favorite items, a space to be yourself
- Lower center-left: a "Pick up!" circle element

Text elements:
- Main title: "Jellyfish-chan's Room Items"
- Badge: "Jellyfish-chan's Room - sharing my room-decor obsessions with you, too."
- Tagline: "Welcome to my fluffy, sweet, slightly dreamlike room"
- Speech bubble: "I'll show you all the room items Jellyfish-chan loves the most"

Color palette: white, pastel lavender, soft lilac, pale gray-violet, touches of pastel blue-pink gradient. The poster is left-heavy with product cards and text; the character portrait occupies the lower right third, slightly overlapping the layout. Keep everything soft, feminine, and cozy: rounded corners on all product photos, bold Japanese headline typography mixed with light handwritten annotations, subtle shadows, clean high-key lighting, social-media-ready editorial collage aesthetic.
