[Input]
- language: Korean
- output_size: 1536x1024

[Purpose]
Korean self-development / information / IT YouTube thumbnail, realistic 16:9 horizontal layout optimized for strong click-through and instant readability.
High-performing creator thumbnail design with a creator-face hero on the left, bold Korean headline on the right, and persuasive YouTube-native details such as a channel handle, small view-bait label, accent emoji/shape, and supporting micro text.

[Composition]
- Left 30%: {피사체} placed as a cropped hero cutout, slightly enlarged so the face and upper torso are immediately recognizable, with a confident expression and natural portrait realism.
- Right 70%: headline area with {메인 텍스트} as the dominant reading element, supported by one highlight treatment on {강조 단어}, short supporting captions, and compact accent graphics that guide the eye.
- Background: {배경} with warm off-white paper texture, faint desk-note / productivity-board details, soft geometric panels, subtle graph-line motifs, and light gray editorial texture that feels like a real creator thumbnail set.
- Overall framing: tight thumbnail crop with energetic diagonal rhythm, subject-to-text balance, strong contrast, and enough surrounding visual context to feel like a polished Korean YouTube thumbnail rather than a blank slide.

[3. CORE STRUCTURE]
- Hero area (left 30%): {피사체} cut out cleanly with natural edge refinement, placed against the textured background with a soft realistic drop shadow and subtle rim separation so the subject feels integrated but still pops.
- Text block (right 70%, upper-middle): {메인 텍스트} set in large bold Korean sans-serif, stacked for fast reading, with strong line separation, crisp black lettering, and slight white keyline or soft shadow for mobile readability.
- Emphasis treatment: {강조 단어} highlighted using a flat yellow marker-style bar behind the text, with a hand-drawn underline stroke or small burst shape nearby to make the key number/phrase instantly noticeable.
- YouTube-native details: include a small channel handle label such as "@growth_lab", a compact category tag like "자기계발 · 돈관리", and a small pill badge reading "오늘부터 시작" near the headline.
- View-bait accents: add a small red arrow, yellow circular callout, or expressive emoji such as "🔥" or "💡" near the highlighted word, scaled to support the headline without blocking it.
- Supporting micro copy: add one short Korean caption below the headline, such as "실천하면 바로 달라집니다", and a tiny lower-right metadata strip like "조회수 128만 · 10분 핵심요약".
- Background handling: {배경} should include tactile paper grain, soft tonal transitions, faint productivity icons, light sticky-note shapes, and subtle chart/arrow motifs related to saving money and self-improvement.

[4. STYLE RULES]
- Typography: Pretendard ExtraBold or Noto Sans KR Black for the main headline, roughly 88–120px visual scale, with compact tracking, crisp edges, and strong mobile-thumbnail readability.
- Secondary typography: use Pretendard SemiBold / Noto Sans KR Bold for channel handle, category tag, and metadata labels at smaller scale, with clean rectangular or rounded-pill label treatments.
- Color palette: black #111111 for main text, yellow #FFE95A for highlight bar, off-white #F4F0E6 and light gray #E8E8E8 for the background family, with optional muted accent gray #7A7A7A and small red accent #FF3B30 for arrows or urgency marks.
- Border/shadow: soft drop shadow on the subject only, about 4px y-offset, 12px blur, 15% opacity; use very subtle text shadow or white keyline only where needed for legibility, avoiding heavy glow or 3D bevels.
- Layout feel: polished Korean education / finance / IT YouTube thumbnail with PPT-like clarity, strong hierarchy, realistic creator presence, and small believable platform details.

[5. VISUAL STYLE]
- Camera / lens: Canon EOS R5 with an 85mm portrait lens look at f/2.8 for the subject cutout, with clean studio-cropped thumbnail aesthetic and realistic facial detail.
- Lighting: soft studio key light from upper-left at about 45°, gentle fill from the front-right, subtle rim separation to keep the subject distinct from the light background.
- Color grade: neutral bright tones with slightly warm off-white paper base, controlled blacks, restrained yellow emphasis, and natural skin tones for a trustworthy information-creator look.
- Texture realism: incorporate fine paper grain, slight marker opacity variation, soft sticker edges, and subtle compression-friendly contrast so the image feels like a real uploaded YouTube thumbnail.

[6. MOOD]
Practical Korean creator thumbnail aesthetic — clean self-improvement YouTube design with the organized clarity of a modern PPT slide, the direct punch of high-performing finance/IT channel thumbnails, and a realistic creator-led atmosphere that feels helpful, urgent, and clickable.

[7. CRITICAL]
- Korean text accuracy: the following strings must appear exactly as written in the rendered image:
  - "월급쟁이가 돈 모으는 5가지 방법"
  - "@growth_lab"
  - "자기계발 · 돈관리"
  - "오늘부터 시작"
  - "실천하면 바로 달라집니다"
  - "조회수 128만 · 10분 핵심요약"
- Layout invariant: left side is the subject hero, right side is the main text and highlight treatment.
- The emphasis word {강조 단어} must be visibly highlighted with a yellow marker-style bar.
- Subject should look natural and confidently expressive, with no distorted face or incorrect anatomy.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
