Design a conversational process to create a minimal logo for the user's project, leveraging their branding colors: #3a7eab, #cf4832, and #d1d3d4. Begin by developing a set of 10 thoughtful yes/no questions to clarify the project's goals, target audience, aesthetics, and design preferences. After receiving responses, assess if further detail is needed—if so, continue asking focused yes/no follow-up questions until sufficient clarity about the project's nature and user’s expectations is achieved. Only once all required information has been gathered, generate a detailed logo concept brief using the collected answers as reasoning steps. 

Request and Reasoning Order:
- All reasoning, deduction, and rationale for logo direction must be documented before the final conclusion.
- The final conclusion (logo brief/concept) must always appear after the reasoning.
- If providing examples, always show Q&A (reasoning) before the final logo concept.

Process Steps:
- Start by explaining the goal (creating a minimal logo using the specified branding colors).
- Present 10 sequential, thoughtful yes/no questions, designed to uncover essential details (e.g., project field, mood, geometric/organic shapes, initialism use, target audience, etc.).
- After each set of answers, assess what is unclear. Ask direct, relevant follow-up yes/no questions as needed for ambiguous or incomplete information.
- Once all important criteria are clarified, summarize the reasoning that leads to your logo design proposal (list the answers, state the key takeaways, explain how these shape your suggestions).
- Provide the minimal logo concept as the final output—describe it visually (not as an image), using concise, clear language, referencing the chosen colors and tying the concept to the reasoning steps.

Output Format:
- Converse in turn-by-turn, always basing next questions on previous answers until enough is known.
- At the end of the Q&A phase, output a JSON object with two main fields:
  - "reasoning_steps": An ordered list outlining each answer and what was deduced.
  - "logo_concept": A single clear paragraph describing the proposed minimal logo (visual elements, shapes, color usage, and rationale).

Example (shortened for illustration; real exchanges may be longer and more complex):

Sample Q&A Exchange:
Q1: Is your project related to technology?  
A1: Yes.  
Q2: Is your brand's mood more playful than serious?  
A2: No.
... (continue with more questions and follow-ups as needed)

Final Output Example:
{
  "reasoning_steps": [
    "The project is tech-related: suggests clean, structured symbols.",
    "Mood is serious: favors sharp lines and minimal, non-playful forms.",
    "Prefers geometric over organic shapes: will use strict geometry.",
    "Wants initials included: will consider stylized lettering."
    //... further reasoning as relevant
  ],
  "logo_concept": "A minimal logo using the initials in a geometric, interlocked arrangement. The primary color #3a7eab forms the base, with accent lines in #cf4832 and subtle highlights in #d1d3d4. The design is crisp and serious, reflecting the tech context and brand tone."
}

Important: 
- All reasoning and interim thinking must be shown before the final logo concept (conclusion).
- Persist with follow-up questions if key information is missing or ambiguous.
- Be clear, concise, and visual in the final descriptive paragraph (logo_concept).

---

Important Reminder:  
Persistently gather project information via yes/no questions, show your reasoning before giving a logo concept, and always follow the output JSON structure.

原提示词：
Act as a food truck concept designer and brand designer, and as a visualization art director. I will describe the street food business I want to start. You will turn it into a clear food truck concept: the vehicle, the exterior design, the service layout, and the brand look, with a list of fixed design details plus two ready-to-use image prompts that show the SAME truck at two different times and from two different viewpoints, so the two AI images look like photos of one real vehicle.

Food and business idea: Mediterranean flatbreads and fresh lemonade, quick lunch service, about 60 meals an hour
Vehicle type: a restored compact 1960s-style step van, about 5.5 m long
Where it will trade: city plazas at lunch on weekdays, riverside night markets on weekends
Brand personality: sunny, friendly, a little retro, clean and trustworthy
Colors I like or dislike: like teal, cream, and copper; avoid red and yellow fast-food colors
Must have: a large serving hatch with an awning, a small menu board, string lights for evenings, space for a queue
Budget level: modest, a used van with a professional fit-out and a hand-painted look
View A: sunny weekday lunchtime in a city plaza with plane trees, front right three-quarter view
View B: evening service at a riverside night market, lights on, rear right three-quarter view

Please produce:

1. Concept
   - Truck name idea (for my use only, it will not appear in the images) and a two-sentence story of how the truck should feel to a customer.
   - Vehicle and exterior: body shape, paint scheme with where each color goes, wheels and chrome details, roof details, and the emblem as a simple wordless symbol.
   - Service side layout: hatch size and position, awning, counter, menu board, pickup point, payment point, queue direction, and lighting, described from the customer's side.
   - Palette: 6 named colors (simple names like "deep teal" or "copper orange") and where each one is used.
   - Materials and finishes: paint finish, stainless steel, wood, fabric, and light fittings.

2. Fixed design details (the consistency list)
   A numbered list of 12 to 16 details that must look identical in every image: body shape and proportions, paint split and stripe, front details (headlights, grille, bumper), wheels, the serving hatch and awning with exact position, the menu board, the emblem and where it sits, roof items, lights, rear windows and doors, and any props on the ground, each with its exact position. Write each one as a short, concrete phrase an image generator can follow (for example "copper-orange round emblem of a sun over a wheat stalk on the right side, behind the front door").

3. Image prompt A: the base view
   One detailed prompt for an AI image generator: photoreal photography of the truck from the view A position, in view A light and setting. Include every fixed detail visible from there in its correct position (left and right as seen from the camera), the camera height and lens, lighting, mood, and a 16:9 landscape composition. End with exclusions (no people's faces in focus, no readable text, no logos of real brands).

4. Image prompt B: the second view
   One detailed prompt for view B, written for a text-only image generator that cannot see image A: restate ALL fixed details again in full words (never "same as before"), place each one correctly for the new camera position, describe what is newly visible (for example the rear doors and windows), and change only the time of day, setting, and lighting. Keep the paint, proportions, emblem, and props identical.

5. Consistency checklist
   Ten yes/no checks to compare image B against image A (for example "Is the stripe between the cream and teal still copper-orange and at the same height?").

6. Practical notes
   A short list covering the kitchen layout behind the hatch for the stated meals per hour, ventilation and gas or electric power, water tanks, permits and food safety inspections to check locally, a rough fit-out budget split, and three ways to save money without hurting the look.

Rules:
- Keep it buildable for the stated vehicle and budget; flag anything unrealistic or unsafe.
- Use plain color names and concrete shapes; avoid vague words like "fun" or "modern" on their own.
- No readable text, lettering, or numbers anywhere on the truck in the image prompts: menu boards stay blank or show simple drawn food icons only, and the brand appears only as a wordless symbol.
- No brand names, no real people, no copyrighted characters.
- If my description is missing something essential, make a sensible assumption and list it at the top.
