[PROMPT]
Create a high-quality professional product photography scene showcasing a distinctive premium packaging design inspired by SUBJECT_NAME.

CORE GOAL
- The packaging must not feel generic.
- The structure, silhouette, surface, and opening experience must carry a unique identity derived from SUBJECT_NAME.
- The final result should feel like a premium industrial design concept, not just a normal box with better graphics.

FORM-DRIVEN PACKAGING LOGIC (CRITICAL)
- First analyze SUBJECT_NAME and infer its natural visual identity:
  • shape language
  • texture character
  • cultural context
  • emotional mood
  • serving or usage form
- Translate that identity into the packaging structure itself.
- The packaging should visually echo the product’s form, rhythm, layers, curves, or silhouette in a refined way.
- Avoid standard rectangular packaging unless it is reinterpreted with distinctive proportions or structural details.

REFERENCE IMAGE LOGIC
- If REFERENCE_IMAGE is provided, analyze it carefully for shape, proportions, color palette, surface texture, and key visual features.
- Preserve the subject’s identity while transforming it into a premium packaging structure.
- Do not directly copy the product literally; reinterpret it into a packaging concept with strong design logic.

STRUCTURE RULES
- Design the package with a memorable silhouette.
- Use structural features such as sleeves, windows, die-cuts, wrap folds, drawer openings, layered trays, curved lids, or reveal panels.
- The structure should feel intentional, elegant, and premium.
- If the subject is a food dish, the package should feel like a refined reinterpretation of the dish’s shape, vessel, or serving culture.

MATERIAL RULES
- Use PRIMARY_MATERIAL if provided.
- If not provided, infer the best material from the subject:
  • organic / local / handmade → natural paper, fiber, kraft, woven texture
  • premium / giftable → rigid board, soft-touch paper, composite, embossed stock
  • fresh / modern food → clean coated board, translucent layer, refined paper-plastic hybrid
- Materials must feel tactile, realistic, and premium.

PATTERN & SURFACE RULES
- Use PATTERN_STYLE if provided.
- If not, infer a subtle surface treatment or pattern from the subject’s identity.
- Pattern must support the structure, not overpower it.
- Use restrained graphic language and premium spacing.
- The package should feel designed, not decorated.

GRAPHIC DESIGN PRINCIPLES
- Strong hierarchy
- Minimal but intentional text
- Generous whitespace
- One focal panel
- Elegant typography
- No clutter
- No generic supermarket packaging feel

LANGUAGE RULES
- All visible text must follow LANGUAGE_MODE only.
- If LANGUAGE_MODE = Thai, all text must be Thai only and 100% correctly spelled.
- No garbled Thai, no broken vowels, no missing tone marks, no approximate Thai text.
- If Thai text cannot be rendered perfectly, reduce text to only the main product name or remove extra copy entirely.
- Better no Thai text than wrong Thai text.

COLOR RULES
- COLOR_TONE controls the main palette.
- If auto, infer the best premium palette from SUBJECT_NAME and material.
- Keep colors restrained, premium, and identity-driven.
- Avoid noisy multi-color graphics unless strongly justified by the subject.

BACKGROUND RULES
- Use a clean solid-color background.
- If BACKGROUND_COLOR is provided, use it exactly.
- If not provided, generate a harmonious solid background color derived from the product, material, and packaging tones.

LIGHTING & SCENE
- Soft, controlled studio lighting with gentle shadows.
- Highlight structural edges, openings, and material texture.
- The object should feel like a design presentation hero shot.

FINAL FEEL
- The result should feel like a premium packaging redesign with a strong signature identity.
- Elegant, memorable, structurally intelligent, photorealistic, and presentation-ready.

[NEGATIVE PROMPT]
generic box, ordinary carton, supermarket packaging, weak silhouette, cluttered graphics, too much text, fake premium look, childish design, random colors, garbled Thai, broken Thai vowels, missing tone marks, cheap retail style
