Generate a 4-Frame Illustrated Onboarding for Mobile Apps

Role: You are an experienced product illustrator, tasked with visually defining the initial user experience for a new mobile application.

Context: We are developing a new mobile application and need a four-frame illustrated onboarding sequence. The goal is to gently guide users through the app's core value proposition and first steps, ensuring a welcoming and intuitive introduction. Each illustration must build on the last, maintaining a consistent visual language, character, and emotional tone.

Task: Generate four distinct illustration prompts, each corresponding to a step in a mobile app onboarding flow. These prompts will be used to generate the final images. Each generated illustration must feature the same main character, depict a specific action related to the app's functionality, and adhere to a warm, inviting color palette. The sequence should convey ease of use and the benefits of the app.

Constraints:
*   **Sequence**: Four separate, sequential illustrations.
*   **Character Consistency**: The primary character must be identical across all four frames in appearance, style, and general demeanor.
*   **Color Palette**: Employ a warm, inviting, and consistent color scheme throughout the entire sequence. Avoid harsh or cool tones.
*   **Narrative Flow**: Each illustration should progress the user's understanding of the app, from initial discovery to a key action.
*   **Rendering Style**: The illustrations should be in a clean, modern, flat illustration style with subtle textures and soft shadows, suitable for mobile UI.
*   **Usage Context**: The illustrations are for a mobile app screen; consider a vertical aspect ratio and clarity within a small display area.
*   **Negatives**: Avoid overly complex backgrounds, sharp angles, dark or cool colors, photorealism, and busy compositions.

Output Format: Provide four separate illustration prompts. Each prompt should clearly describe:
1.  **Subject**: The main character performing a specific action related to the app.
2.  **Composition**: The character's pose, any supporting elements, and overall framing.
3.  **Palette**: Reinforce the warm color scheme.
4.  **Rendering Style**: Reiterate the clean, modern, flat style.
5.  **Usage Context**: Explicitly state "mobile app onboarding illustration".
6.  **Negatives**: List specific elements to avoid for consistency.

**Illustration Prompt 1/4: Welcome & Discovery**
Subject: A friendly, diverse character ({{main_character_description}}) smiling, holding a smartphone displaying the app's logo and a welcoming message.

Negatives: dark colors, complex patterns, photorealism, harsh lighting, inconsistent character.

**Illustration Prompt 2/4: Value Proposition - {{app_feature_1}}**
Subject: The same character ({{main_character_description}}) interacting with the app's interface on their phone, specifically demonstrating {{app_feature_1}}. Perhaps they are tapping a button or observing a positive outcome on screen.
Composition: Over-the-shoulder view of the character, focusing on the phone screen with a clear visual representation of {{app_feature_1}} in action. Simple, warm background.
Palette: Maintaining soft oranges, warm yellows, and muted creams.
Rendering Style: Clean, modern, flat illustration with subtle texture, soft shadows, vector art aesthetic.
Usage Context: mobile app onboarding illustration.
Negatives: dark colors, complex patterns, photorealism, harsh lighting, inconsistent character.

**Illustration Prompt 3/4: Feature Highlight - {{app_feature_2}}**
Subject: The character ({{main_character_description}}) actively benefiting from {{app_feature_2}}. For example, if {{app_feature_2}} is "tracking progress", show them looking satisfied at a progress bar on their phone.
Composition: The character is engaged, perhaps with a thought bubble or subtle environmental cues (e.g., a small plant) reinforcing the positive outcome. Focus on the character's expression and the app's visual feedback.
Palette: Continuing soft oranges, warm yellows, and muted creams.
Rendering Style: Clean, modern, flat illustration with subtle texture, soft shadows, vector art aesthetic.
Usage Context: mobile app onboarding illustration.
Negatives: dark colors, complex patterns, photorealism, harsh lighting, inconsistent character.

**Illustration Prompt 4/4: Call to Action - Get Started**
Subject: The character ({{main_character_description}}) confidently looking forward, perhaps giving a thumbs-up or reaching out, with a prominent "Get Started" button or similar call to action visible on their phone screen.
Composition: Frontal or slightly angled view of the character, conveying readiness and enthusiasm. The phone is visible but secondary to the character's positive gesture.
Palette: Consistent soft oranges, warm yellows, and muted creams, perhaps with a slightly brighter accent for the call to action.
Rendering Style: Clean, modern, flat illustration with subtle texture, soft shadows, vector art aesthetic.
Usage Context: mobile app onboarding illustration.
Negatives: dark colors, complex patterns, photorealism, harsh lighting, inconsistent character.
