通用專業模板
============
Create [DELIVERABLE] for [BRAND / AUDIENCE / CHANNEL].

GOAL
[WHAT THE IMAGE MUST COMMUNICATE OR HELP THE USER DO]

REFERENCES
Image 1 = [ROLE]. Image 2 = [ROLE]. Image 3 = [ROLE].

CONTENT
[SUBJECT, ACTION, SCENE, VERIFIED FACTS]

LAYOUT
[RATIO, GRID, HIERARCHY, SAFE AREA, READING ORDER]

TEXT — EXACT
"[HEADLINE]" / "[SUBHEAD]" / "[LABELS]"

VISUAL SYSTEM
[STYLE, COLORS, TYPE STYLE, MATERIALS, LIGHT, CAMERA]

PRESERVE / QA
[FIXED ELEMENTS, ACCURACY, ONE-TIME TEXT, HUMAN REVIEW]

01｜多參考圖產品 Mockup
======================
Combine the supplied references into one high-fidelity commercial product mockup.

REFERENCE ROLES
Image 1: exact [PRODUCT], preserving geometry, label, color and material.
Image 2: exact packaging dieline and front-panel hierarchy.
Image 3: approved brand palette and typography mood only.
Image 4: target retail shelf environment.

Create a 4:5 three-quarter hero photograph with the product and package grouped on the lower-right, headline space upper-left. Match shelf perspective, light, reflections, scale and contact shadows. Keep Image 1 and Image 2 structural details unchanged. Apply Image 3 only to approved color fields and supporting graphic texture. Output a realistic retail campaign draft suitable for manual prepress and label verification.

02｜複雜品牌海報
===============
Design a premium 4:5 launch poster for [BRAND] and [PRODUCT].

LAYOUT
Use a modular Swiss-inspired grid. Place one photorealistic product hero in the lower center, a large headline block at upper left, three concise feature labels aligned vertically on the right, and a small legal-copy placeholder at the bottom.

EXACT TEXT
Headline: "[HEADLINE]"
Feature labels: "[FEATURE 1]", "[FEATURE 2]", "[FEATURE 3]"
Each appears exactly once. Use bold geometric sans-serif for the headline, medium sans-serif for labels, high contrast and generous spacing.

VISUAL
Brand colors [HEX 1], [HEX 2], [HEX 3], precise product materials, refined studio light and a clean production-ready hierarchy. Keep legal text and official vector Logo for post-production review.

03｜搜尋 Grounding 資訊海報
==========================
Search for the current verified [WEATHER / PUBLIC EVENT DATE / MARKET FACT] for [LOCATION OR TOPIC] on [DATE]. Summarize only the minimum facts needed for a visual: [REQUIRED FIELDS]. Then create a 4:5 editorial information poster translating those facts into one clear hero scene and a compact data card.

Exact title: "[TITLE]".
Data labels: "[LABEL 1]", "[LABEL 2]", "[LABEL 3]".
Use a direct reading order, large accessible type, source-note space at the bottom and visually accurate conditions. Return the image plus a text list of the facts used so a human can verify the sources before publication.

04｜品牌視覺系統提案板
=====================
Create a 16:9 brand direction board for [BRAND / INDUSTRY] aimed at [AUDIENCE]. Arrange six clearly separated zones: hero visual, color palette, typography direction, material texture, photographic lighting, and two example applications. Use approved colors [HEX LIST]. Include exact labels "HERO", "COLOR", "TYPE", "MATERIAL", "LIGHT", "APPLICATION" once each. The board feels coherent and presentation-ready, with consistent margins, a restrained grid and realistic mockups. Use placeholder brand marks; final trademark artwork will be inserted later.

05｜跨語言包裝在地化
===================
Translate and edit only the specified text on the supplied package image.

SOURCE → TARGET
"[SOURCE LINE 1]" → "[TRADITIONAL CHINESE LINE 1]"
"[SOURCE LINE 2]" → "[TRADITIONAL CHINESE LINE 2]"

Match the original text regions, hierarchy, alignment, baseline, print texture, color, curvature and perspective. Preserve the exact package geometry, brand mark, barcode, regulatory icons, all other copy, product color, lighting, camera and background. Each target line appears once. Return a legible proof for bilingual, legal and prepress review; do not treat generated text as final artwork.

06｜授權人物跨場景品牌系列
=========================
Use the authorized adult person from Image 1 as the only principal character. Preserve facial proportions, real age, skin tone, hairstyle and individual features across all outputs. Use Image 2 for the approved navy wardrobe and Image 3 for the office architecture.

Create a three-frame contact sheet: Frame A, medium portrait beside the window; Frame B, seated and reviewing a prototype; Frame C, speaking naturally to a small team. Keep wardrobe, time of day, window-light direction, skin rendering and office geography consistent. Each frame has clean right-side copy space and an honest editorial corporate-photography finish. Label frames only as "A", "B", "C".

07｜建築材質方案編修
===================
Edit the supplied approved building visualization. Change only the façade material in the marked elevation zones from [ORIGINAL MATERIAL] to [NEW MATERIAL / COLOR / MODULE SIZE]. Preserve site, massing, floor count, structural grid, windows, entrances, balconies, landscape, neighboring context, camera, crop, time of day and shadows. Make the new material physically buildable with coherent joints, corners, flashing and weathering behavior. Match the original perspective and light. Return a side-by-side two-panel comparison labeled exactly "OPTION A" and "OPTION B" for architect review.

08｜電商商品詳情頁長圖
=====================
Design a 9:16 mobile product-detail visual for [PRODUCT] using the supplied exact product reference and verified facts.

SECTIONS FROM TOP TO BOTTOM
1. Hero product and headline "[HEADLINE]".
2. Three feature cards: "[FEATURE 1]", "[FEATURE 2]", "[FEATURE 3]".
3. Material close-up with label "[MATERIAL]".
4. Usage scene based only on [VERIFIED USE].
5. CTA placeholder "[CTA]".

Use [BRAND HEX COLORS], a consistent grid, large mobile-readable type, restrained iconography, accurate product geometry and realistic material lighting. Keep claims factual and reserve all legal copy for human-approved post-production.

09｜四格影片分鏡板
=================
Create a coherent four-panel 16:9 storyboard sheet for a 15-second [BRAND] film. Use the authorized adult character and product references consistently.

Panel 1 — Establishing: [LOCATION AND TIME].
Panel 2 — Action: [CHARACTER INTERACTS WITH PRODUCT].
Panel 3 — Detail: [MATERIAL OR FEATURE CLOSE-UP].
Panel 4 — Resolution: [FINAL EMOTION AND COPY SPACE].

Keep character identity, wardrobe, product, screen direction, light and color continuous. Use cinematic live-action frames with clear shot progression: wide, medium, detail, hero. Label each panel exactly "01", "02", "03", "04". Provide a short text caption under each panel for director review.

10｜資料視覺化
===============
Create a precise 16:9 executive infographic using only this verified dataset: [PASTE DATA AND UNITS].

ANALYTICAL TASK
Show [COMPARISON / TREND / COMPOSITION] and emphasize [ONE DECISION-RELEVANT INSIGHT]. Maintain correct numerical proportions and units.

LAYOUT
Title "[TITLE]" at top left, one main [BAR / LINE / DONUT] chart, three concise callouts and a source line "[SOURCE]" at bottom. Use brand colors [HEX LIST], white background, dark text, accessible contrast and presentation-readable labels. Render every number exactly as supplied. Return the image plus a text transcript of every displayed value for verification.

11｜汽車多素材合成廣告
=====================
Use Image 1 as the exact [YEAR MAKE MODEL] source, Image 2 as the approved wheel and trim reference, Image 3 as the coastal location, and Image 4 as color-grade inspiration only. Create a 16:9 three-quarter front hero photograph at blue hour. Preserve the car’s body proportions, grille, lights, badges and panel lines; apply the approved wheel and trim precisely. Match the road’s perspective, tire contact, environmental reflection and shadow. Apply Image 4 only to color balance and contrast. Keep left-side headline space and return an unlettered production master.

12｜精準單項修圖
=================
Edit the current image with one controlled change.

CHANGE
[ONE EXACT CHANGE]

PRESERVE EXACTLY
[IDENTITY, PRODUCT GEOMETRY, CAMERA, CROP, POSE, LAYOUT, ALL OTHER TEXT, LOGO, MATERIALS, LIGHT DIRECTION, BACKGROUND, SHADOWS]

MATCH
Match the existing perspective, scale, white balance, print texture, occlusion, reflection and edge quality. Keep every preserved element consistent. Return one corrected image and a one-sentence text summary of what changed for approval tracking.

失敗修復
========
文字仍有誤：先在對話中確認最終文案，再要求排版；縮短文字；要求文字 transcript；正式稿後製。
多圖角色混淆：將每張圖命名並寫清 only for / preserve / apply to；減少同輪變更。
推理過度創作：提供 VERIFIED FACTS 與 PRESERVE，要求回傳採用事實清單。
資料圖比例錯：提供原始數值與單位，指定圖表型態，要求文字 transcript 做數值比對。
人物／商品漂移：分成身份基準 → 場景 → 姿態 → 文案四輪，不一次完成全部。
