[Purpose]
Instagram Reels cover for a 100-book reading challenge, designed as a bookstagram-style vertical cover with editorial Korean copy, collectible reading-log details, and social-card interface elements.
A shareable Reels thumbnail that feels like a personal reading archive poster, combining a cozy book hero image, progress tracking, and Instagram-native micro details.

[Composition]
- Main subject placement: the {챌린지 종류} hero area dominates the center-left 60% of the frame, with the {모델 자세·표정} placed beside or slightly behind the featured book stack so the reading story feels personal and realistic.
- Background treatment: creamy paper-like backdrop with subtle warm texture, faint bookshelf shadows, amber desk-lamp glow, scattered bookmark tabs, pencil marks, and a few real reading-log details that support the bookstagram mood.
- Framing: vertical {비율} layout with an editorial thumbnail hierarchy: strong title at top, book-and-reader hero in the middle, progress interface and caption sticker at the bottom.
- Use {컨셉·테마} to anchor the visual narrative, {비주얼·소품} for the layered reading-progress interface, and {컬러 톤} as the dominant palette.
- Add realistic Instagram-card metadata: {인스타 핸들}, {날짜 라벨}, {위치 라벨}, {해시태그}, save/share micro icons, and a small CTA so the cover feels ready to publish.

[3. CORE STRUCTURE]
1. Top headline zone (upper 18%): place the main Korean challenge title in a bold, high-contrast masthead style, aligned slightly left of center, with a compact issue label such as “READING LOG 042” and a small date chip using {날짜 라벨}.
2. Hero zone (mid 45%): feature the reading-challenge subject, a book cover hero inspired by {책 제목}, layered book spines, bookmark ribbons, margin notes, and the supporting {모델 자세·표정}; use realistic paper shadows and slight overlap to create depth.
3. Social metadata strip (upper-mid or side label): include {인스타 핸들}, {위치 라벨}, a tiny profile-dot avatar, and micro interface marks like “↗ 공유” and “💾 저장” as small but readable social details.
4. Info stack zone (mid-lower 22%): add {인용구}, {별점}, and {진행률} as intentional UI-like reading-log elements; show a progress bar with warm amber fill, a small percentage chip, and a neat divider line.
5. Caption callout zone (lower 15%): render {릴스 카피} as a compact punchline-style sticker or tape label, then add {해시태그} and {CTA 문구} as secondary Instagram caption details.
6. Polish pass: apply subtle depth, soft paper shadows, crisp typography edges, realistic book-cover sheen, and tactile printed-card texture so the layout reads like a polished bookstagram editorial thumbnail.

[4. STYLE RULES]
- Typography: use Pretendard ExtraBold or Noto Sans KR Black for the main headline, Pretendard Medium for secondary text, and a handwritten accent style only for tiny annotation details; headline size should feel poster-like and mobile-readable.
- Color palette: cream #F4ECDD, charcoal #2A2A2A, warm amber #D08A3A, muted brown #7A5A3A, soft beige #DCCBB4.
- Border/shadow: use soft drop shadows with 4px y-offset, 12px blur, and 15% opacity; rounded card edges may appear on caption stickers, progress modules, bookmark tabs, and social metadata chips.
- Decorative graphics: include tasteful bookish elements such as page tabs, underline strokes, star icons, tiny calendar chip, reading-progress badge, and subtle paper grain that reinforce the reading-log theme.
- Text hierarchy: main challenge title first, then book title/caption, then progress and social metadata; all Korean text should be crisp and intentionally typeset.

[5. VISUAL STYLE]
- Camera / lens: editorial product-photo look with a full-frame 50mm lens at f/2.8, lightly compressed perspective, designed like a polished social-media cover rather than a documentary photo.
- Lighting: soft window light from upper-left at about 45°, gentle fill from the right, and a faint warm rim to separate the hero from the background.
- Color grade: cream-and-amber reading-club palette with charcoal anchors, warm paper highlights, and slightly desaturated shadows for a refined bookstagram finish.
- Material rendering: matte paper cards, slightly glossy book jacket, soft fabric sleeve or table linen texture, and realistic printed ink edges for the caption sticker and progress panel.

[6. MOOD]
Premium bookstagram editorial — feels like a Kinfolk-style reading spread translated into a Reels cover, with cozy late-night reading energy, collectible challenge-tracker details, and a friendly Instagram community tone.

[7. CRITICAL]
- Korean text accuracy: 반드시 정확히 보여야 하는 메인 문자열: "100권 챌린지 #42 — 미드나잇 라이브러리".
- 반드시 포함할 보조 문자열: "@book.log_100", "2026.05.01 · 서울", "읽은 책 42 / 100", "★★★★☆ 4.5".
- 반드시 포함할 소셜/캡션 문자열: "#북스타그램 #독서기록 #100권챌린지", "💾 저장", "↗ 공유", "저장하고 다음 책 같이 읽기".
- The reading-progress bar, star rating, quote element, date/location chip, handle label, and save/share micro icons must appear as intentional Instagram reading-log UI details.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
- Cropped or illegible Korean text
- Face or body distortion
