星穹偶像角色海报

Goal: Create a highly detailed anime idol character showcase poster featuring {argument name="character name" default="a mysterious starlight idol"}, with a dark celestial concert aesthetic and ornate trading-card layout.

Canvas: Vertical 3:4 poster, richly detailed, dark navy and warm gold palette, glossy premium illustration finish. The design should look like an idol character card collection page with decorative borders, film-strip accents, tiny stars, confetti, and elegant gothic arches in the background.

Layout: Use exactly 7 character illustrations total: 1 large central full-body portrait and 6 smaller surrounding portrait panels. The 6 smaller panels are numbered in small gold text as 01, 02, 03, 04, 05, and 06. Arrange them as two panels across the top corners, two panels in the middle left and middle right, and two panels along the lower left and lower right, framing the central figure. The central portrait is the largest, inside an ornate rounded rectangular gold frame with a crown-like decorative crest at the top and a small plaque at the bottom showing five small gold icons: star, star, crown, star, star.

Subject details: The character is a young anime idol girl with {argument name="hair color" default="very long glossy black hair"}, straight bangs, long flowing side strands, and small silver star hairpins. Her face is intentionally obscured in every panel by a soft rectangular blur, while the rest of the illustration remains sharp. She wears a white short-sleeve puff blouse with frilled neckline, black ribbon bow at the chest, black choker with white frill trim, black fingerless gloves, silver bracelets, a high-waisted dark navy pleated skirt with a galaxy sparkle gradient, white underskirt ruffles, black belt with silver ring buckle, dangling silver star chains on the hip, black thigh garters, and idol accessories. The overall outfit theme is {argument name="outfit theme" default="gothic celestial idol"}.

Panel poses: Include exactly these 6 numbered side-panel variations: 01 shows an upper-body idol pose holding a microphone near the lower right, one hand near the chest; 02 shows an upper-body pose touching the choker or collar with one hand; 03 shows a waist-up pose holding a microphone downward in one hand; 04 shows an upper-body pose with one hand near the face making a playful idol gesture; 05 shows a side/back three-quarter pose looking over the shoulder with long hair flowing dramatically; 06 shows a cheerful upper-body pose with both hands raised in small finger-heart or pointing gestures and a large microphone floating near the right side. The central portrait shows the idol standing full-body, one hand making a peace sign beside the face, skirt flared outward, confident concert-poster stance.

Background and decoration: Set all portraits inside a grand cathedral-like hall with tall arched windows glowing with warm light, dark columns, night-sky sparkles, floating confetti, lens flares, and magical star particles. The bottom center outside the portraits contains a large gold compass star emblem, laurel branches, and a curved film-strip ribbon. Add tiny gold numbering, thin ornamental borders, subtle film sprocket marks, and a polished collectible-card feel.

Visual style: High-resolution anime illustration, crisp line art, luminous highlights, glossy hair shading, dramatic rim lighting, intricate fabric folds, deep navy shadows, gold accents, magical idol atmosphere, symmetrical composition, premium poster design.

Constraints: Use exactly 7 character depictions and exactly 6 numbered side panels labeled 01 through 06. Keep all faces covered by the same soft blur effect. Do not add readable text besides the small panel numbers and decorative icons. Avoid logos, watermarks, and extra characters.
