Add Roof Rack or Cargo Box

ROLE
Act as a professional automotive photo retoucher and vehicle visualization specialist. Use the uploaded source as the authoritative reference for the content that must remain unchanged. Perform a controlled edit tailored to the requested result.

EDIT
Add [ROOF ACCESSORY] to the roof of [TARGET VEHICLE].

PRIMARY OBJECTIVE
Execute “Add Roof Rack or Cargo Box” clearly and convincingly. The requested change should be visible and intentional, with coherent boundaries, depth and material response. Follow the edit-specific rules below rather than redesigning unrelated content.

EDITING PRIORITY
1. Apply the requested change to the correct target.
2. Preserve recognizable identity, geometry and details outside that change.
3. Integrate the result with coherent lighting, perspective and occlusion.
4. Protect fine edges and remove unintended artifacts.

EDIT-SPECIFIC INSTRUCTIONS
- Align the accessory with the vehicle’s roof plane and longitudinal direction.
- Use plausible mount positions and visible contact points; do not float rails above the roof.
- Keep the load centered and proportionate, with practical-looking clearance from antenna and hatch.
- Preserve roof glass and existing rails where visible, accommodating them without deforming the roof.
- Update local contact shadows and reflections while leaving body and wheels intact.
- Show a visual preview only; do not invent certified load ratings, guaranteed fitment or product branding.

STRICT PRESERVATION RULES
- Preserve the source composition, camera position, crop, aspect ratio, perspective and all content outside the requested edit. A requested change to lighting, geometry, materials or placement is permitted only within its described scope.
- Preserve untargeted people, animals, objects, accessories, permanent features and readable markings.
- Do not introduce additional subjects, props, logos or decorative text beyond the requested edit.
- Where an intentional change exposes a previously hidden area, reconstruct only what is necessary from adjacent visual evidence; do not invent unrelated features.
- Keep the effect confined to its intended area and directly connected shadows, reflections or occlusion. Do not apply unrelated beauty retouching, global grading or sharpening.

REALISM & INTEGRATION
- Match perspective, relative scale and attachment or ground contact to the scene.
- Make lighting and reflections coherent with the target material and the requested transformation. Preserve unrelated light sources and their effects.
- Use clean but natural boundaries. Maintain appropriate hair, fur, textile or surface detail rather than smooth cutout edges.
- Match focus, blur and grain to the surrounding image unless the requested style explicitly changes them.

ARTIFACT PREVENTION
Avoid warped geometry, duplicated parts, smeared textures, broken reflections, halos, inconsistent scale, mismatched focus and corrupted text. Do not make detail sharper or more elaborate than the source supports. Respect the specific stylization requested without letting it change unrelated content.

QUALITY CONTROL
Compare the result with the source before finalizing. Verify the correct target and requested appearance, count visible parts, inspect boundaries and check perspective, contact, shadows and reflections. Confirm that protected content and recognizable features have not changed and that no unintended objects or text appeared.

OUTPUT
Return one final edited image only at the original aspect ratio. Follow the framing rules above. Do not add captions, explanatory text, watermarks, borders or before/after comparison panels.
