[Purpose]
Square marathon finish-line 인증 card for social media sharing, designed as a realistic personal race recap and completion celebration post.
Built for an individual runner’s completion moment with clear Korean labels, race-day metadata, achievement-card decoration, and shareable Instagram-feed energy.

[Composition]
- Center hero placement: {참고 이미지} occupies the central 60% of the frame, slightly above the exact vertical midpoint so the footer information band and race-stat details remain clearly visible.
- Background treatment: soft light gray to white gradient backdrop layered with subtle asphalt grain, faint route-map linework, light finish-line stripe texture, and a few restrained confetti flecks to make the card feel like a real marathon day keepsake.
- Spacing and framing: preserve {비율} as a perfectly square composition with balanced left-right structure and no tilt; use editorial alignment so the runner, title, stats, badges, and captions feel intentionally arranged.
- Visible Korean text anchors: {대회 이름}, {완주 시간}, {거리}, {한 줄} should be clearly readable and balanced around the hero image.
- Add realistic completion-card details: a small top date label like "2026.05.01", a compact "FINISHER" tag, a tiny page-style marker "기록 카드 01", and a small caption strip reading "오늘의 완주 기록" without overpowering the main placeholders.

[3. CORE STRUCTURE]
1. Header area (top 15%): place {대회 이름} centered in bold black headline treatment, with compact line height and event-card hierarchy. Add a small uppercase label above it, "MARATHON FINISHER", and a tiny Korean date/edition line such as "2026년 5월 기록" or "러너 인증 카드".
2. Hero area (mid 60%): place {참고 이미지} as a clean cut-out, centered and slightly elevated, with a realistic soft shadow beneath the body and crisp edge separation from the pale textured background. Add subtle race-day graphic layers behind the runner, such as a translucent route-map curve, split-marker ticks, and a finish-line tape stripe crossing behind the subject.
3. Footer information band (bottom 25%):
   - Left block: "완주 시간: {완주 시간}" aligned left, medium weight, easy to scan at a glance, with stable baseline alignment.
   - Center block: "거리: {거리}" centered directly under the hero, matching the visual weight and scale of the left block.
   - Right block: {한 줄} aligned right, slightly larger than the labels so it reads as the celebratory punch line.
   - Add a fine divider line above the footer and small supporting micro-labels such as "TIME", "DISTANCE", "MOMENT" beneath each block for a realistic sports-record-card feel.
4. Secondary balance: enrich the card with believable achievement details: tiny stat chips reading "PACE", "SPLIT", "FINISH", a small barcode-like race record strip, a model/runner credit line such as "RUNNER CREDIT / 개인 완주 기록", and a subtle certificate-style corner ornament that does not imply an official seal.

[4. STYLE RULES]
- Typography: Pretendard Bold for {대회 이름} at headline size, Pretendard SemiBold for footer labels, Noto Sans KR Regular for supporting text; use crisp anti-aliased Korean text with sharp legibility.
- Color palette: #111111 for primary text, #4B4B4B for secondary labels, #FFFFFF for the background, #EDEDED for the gradient midpoint, with cool gray accents, faint blue-gray route lines, and a small warm highlight accent for celebration details.
- Border/shadow: soft drop shadow around {참고 이미지}, 5px y-offset, 10px blur, 20% opacity; use thin editorial divider lines, translucent stat chips, and subtle layered paper-card depth.
- Decorative elements: include realistic marathon recap graphics such as route trace, timing-strip marks, finish-line pattern, confetti specks, small number-tag shapes, and understated badge labels like "FINISHER" or "PERSONAL RECORD" as decorative design text only.

[5. VISUAL STYLE]
- Camera / lens: Canon EOS R5 with RF 50mm f/1.8 lens, eye-level framing, shallow subject separation while preserving documentary clarity.
- Lighting: natural daylight from above and slightly front-left, diffused like overcast outdoor finish-line light, even exposure with tactile shadows on the card layers and runner cut-out.
- Color grade: neutral white and cool gray base with a slight warm skin-tone lift, clean editorial fitness-post look with realistic race-day texture and polished social graphics.

[6. MOOD]
Energetic personal victory card — inspired by a Nike run recap post, marathon finisher certificate styling, and premium sports editorial design.

[7. CRITICAL]
- Korean text accuracy: "{대회 이름}", "완주 시간: {완주 시간}", "거리: {거리}", "{한 줄}" must appear exactly as written.
- Additional Korean text may include short realistic labels such as "오늘의 완주 기록", "러너 인증 카드", "2026년 5월 기록", "기록 카드 01", and "개인 완주 기록".
- Layout invariant: the hero cut-out must remain centered in the middle area, and the three footer text blocks must stay left / center / right in that order.
- Keep the image as a square 1:1 composition with no rotation or tilt.

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