[USER INPUT — REQUIRED AT TOP]

COUNTRY_NAME: Japan
OBJECT_THEME:
BACKGROUND_STYLE: Solid Black

LAYOUT_MODE: FREEFORM_DENSE
LABEL_MODE: OFF
LABEL_LANGUAGE: Thai
LABEL_ACCURACY_MODE: {Fixed: 100% correct spelling and grammar}

[CORE LOGIC — DO NOT DISPLAY]

1. Object selection rule:
   → If OBJECT_THEME is provided:
     - Use OBJECT_THEME exactly as specified.
     - Maintain real-world material logic, thickness, edges, and collectible feel.
   → If OBJECT_THEME is NOT provided:
     - Intelligently infer the most culturally accurate souvenir object
       based on COUNTRY_NAME, prioritizing:
       fridge magnet → stamp → miniature collectible → postcard-style object
     - The inferred object must feel authentic and globally recognizable.
     - NEVER choose abstract objects, modern tech devices, or futuristic digital items.

2. Background rule:
   → If BACKGROUND_STYLE is provided: follow it exactly.
   → If not provided: infer a culturally appropriate warm vintage surface.
   → Keep background as a single unified surface with consistent texture.
   → No busy scenery.

3. Layout mode control (CRITICAL):
   → If LAYOUT_MODE = GRID:
     - Arrange items using an implicit, physical grid.
     - Grid must feel collectible and handcrafted, not digital UI.
     - Use alignment and spacing only; no drawn lines or frames.
     - Each cell contains one object or one tight mini-group.
   → If LAYOUT_MODE = FREEFORM_DENSE:
     - DO NOT use grid logic.
     - Arrange items in a dense, organic, freeform layout.
     - Placement should feel intuitive, spontaneous, and hand-arranged,
       similar to a souvenir table, collector board, or market display.
     - Overlaps, rotations, scale variation, and irregular spacing are allowed.
     - Visual density must be high, filling the frame richly and generously.
     - Avoid symmetrical or evenly spaced grid patterns entirely.

4. Composition density rule:
   → Total items: 14–24 key objects (higher density preferred).
   → Objects may partially overlap but must remain readable.
   → All elements must be culturally and geographically accurate
     for COUNTRY_NAME.
   → NEVER mix symbols from other countries.

5. Label mode control (CRITICAL):
   → If LABEL_MODE = ON:
     - EVERY souvenir object MUST have exactly one visible label.
     - No object is allowed to remain unlabeled.
     - Leaving any object without a label is considered an error.
     - If a specific name is 100% certain, use that name.
     - If there is ANY uncertainty, use a universally safe category label.
     - Never invent or guess specific names.
   → If LABEL_MODE = OFF:
     - DO NOT display any labels, stickers, captions, or written language.
     - Remove all text elements except the main title plaque.
     - Objects must communicate identity purely through form and symbolism.

6. Text correctness rule (ENFORCED — when LABEL_MODE = ON):
   → All labels must be:
       - 1–4 words only
       - 100% correct spelling and grammar in LABEL_LANGUAGE
       - High-confidence only
   → Allowed safe category labels include:
       “Landmark”, “Street Food”, “Handcraft”,
       “Traditional Costume”, “Architecture”, “Heritage Item”
   → No misspellings, no garbled text,
     no random characters, no placeholder text.

7. Label style rule (when LABEL_MODE = ON):
   → Labels appear only as small physical sticker strips.
   → Beige or light neutral tones only.
   → Elegant, culturally appropriate font
     (Thai font for Thai, classic serif/sans for English).
   → No modern UI overlays.
   → No long text.

[PROMPT — IMAGE GENERATION]

Create a hyper-detailed, realistic 3D collectible souvenir composition
themed around {COUNTRY_NAME}.

Use {OBJECT_THEME} as the physical souvenir form if provided.
If not provided, intelligently infer the most culturally accurate
and globally recognizable tourist souvenir object for {COUNTRY_NAME}
following the defined fallback order.

Arrange all souvenirs according to {LAYOUT_MODE}.

If FREEFORM_DENSE:
The composition must feel rich, spontaneous, and overflowing —
like a carefully curated yet organic collector’s spread.
Objects vary in size, angle, and placement,
creating visual rhythm and layered depth without strict structure.

If GRID:
Use a subtle, physical grid logic formed only by alignment and spacing,
never digital UI lines.

Display everything on a {BACKGROUND_STYLE or inferred culturally appropriate vintage material background}
with visible natural texture and subtle wear.

At the top of the composition,
include a vintage-style physical title plaque reading:
“{COUNTRY_NAME} {COUNTRY_NAME (uppercase)}”.
The title must appear engraved, embossed, enamelled,
or printed on a real material (wood, metal, ceramic),
never as digital text or UI.

Each souvenir object must have:
- crisp 1–2 mm white edge outline
- realistic thickness
- subtle bevels
- physically plausible materials
  (enamel, resin, ceramic, wood, metal)

Lighting and camera:
- professional product-photography lighting
- soft, realistic shadows
- slightly top-down angle
- crisp focus
- rich micro-textures
- accurate cast shadows for every object

Content requirements:
- At least one ancient or sacred landmark
- One political or historical monument
- One traditional residential or vernacular architecture element
- One key natural or geographic landmark (if culturally central)
- One traditional costume or performing arts element
- One authentic craft or decorative pattern
- One traditional transport or lifestyle object
- 1–2 ceremonial or heritage artifacts
- 2–4 everyday foods or drinks strongly associated with {COUNTRY_NAME},
  shown with accurate serving ware and realistic texture

FINAL ENFORCEMENT:
- FREEFORM_DENSE mode must NOT resemble a grid.
- GRID mode must NOT resemble modern UI.
- If LABEL_MODE = ON → every object has exactly one label.
- If LABEL_MODE = OFF → no labels except the title plaque.
- No guessing names.
- No weather indicators.
- No temperatures.
- No modern UI.
- No mixing countries.

Final aesthetic:
A rich, museum-style collectible souvenir composition —
dense, tactile, culturally precise,
and visually satisfying.
