        A great prompt is a recipe for a great image. Structure your ideas clearly for the best results.
        - **Subject**: Start with the main focus. *'A majestic lion', 'A futuristic city', 'A portrait of a queen'.*
        - **Medium**: How was it made? *'Oil painting', 'Photograph', '3D render', 'Pencil sketch'.*
        - **Style**: The artistic influence. *'Impressionism', 'Cyberpunk', 'Art Nouveau', 'by Van Gogh'.*
        - **Setting & Context**: Where and when? *'in a sun-drenched meadow', 'on a distant alien planet', 'during the Roaring Twenties'.*
        - **Composition**: How is it framed? *'Wide-angle shot', 'Close-up portrait', 'Bird's-eye view'.*
        - **Lighting**: How is it lit? *'Soft morning light', 'Dramatic cinematic lighting', 'Neon glow'.*
        - **Color & Mood**: The emotional tone. *'Vibrant and energetic', 'Monochromatic and somber', 'Pastel and dreamy'.*

        Control the virtual camera to frame your subject perfectly.
        - **`Wide-angle shot`, `Panoramic`**: Captures a broad scene, great for landscapes.
        - **`Close-up`, `Macro shot`**: Focuses on small details.
        - **`Portrait`, `Full-body shot`**: Specifies how much of a character is visible.
        - **`Bird's-eye view`, `Top-down view`**: Looks directly down on the scene.
        - **`Low-angle shot`, `Worm's-eye view`**: Looks up from below, making subjects seem powerful.
        - **`Dutch angle`, `Tilted frame`**: Creates a sense of unease or dynamism.

        Certain words act as powerful modifiers. Use them to guide the AI.
        - **Quality Boosters**: `masterpiece`, `best quality`, `highly detailed`, `intricate details`, `4k`, `8k`, `UHD`. These encourage the AI to spend more effort on detail.
        - **Realism**: `photorealistic`, `realistic`, `DSLR photo`, `shot on film`.
        - **Artistic Mediums**: `oil painting`, `watercolor`, `charcoal sketch`, `digital art`, `sculpture`.

        - **Weighted Blend**: You can sometimes influence the mix with parentheses, though this is model-dependent. *'A (Van Gogh:1.2) and (Miyazaki:0.8) style cat'.*

        - **Remove Unwanted Objects**: `no people, no cars, no buildings`.
        - **Control the Style**: If you want a photo, you might add `painting, drawing, illustration, cartoon` to the negative prompt.

    "**Technical Background:**\n"
    "- DreamCanvas originally relied on **Gemini 1.5 Flash (experimental image generation)** "
    "for core image synthesis and editing capabilities.\n"
    "- In late 2025, Google discontinued the `gemini-1.5-flash-exp-image-generation` endpoint, "
    "which previously supported integrated multimodal generation and editing workflows.\n\n"
    
    "**Current Architecture:**\n"
    "- Image generation now uses **Hugging Face Inference API**.\n"
    "- Primary model: **FLUX.1-schnell (Black Forest Labs)** for fast diffusion-based synthesis.\n"
    "- Text reasoning and description generation use **Qwen 2.5 Instruct models**.\n\n"
    
    "**Why Some Utilities Are Unstable:**\n"
    "- Gemini previously supported **native multimodal operations** (image + text reasoning).\n"
    "- FLUX models are **pure diffusion generators** and lack built-in editing APIs.\n"
    "- Several tools (inpainting, contextual edits, semantic adjustments, etc.) now require "
    "custom pipelines or external models.\n"
    "- Hugging Face inference also introduces **rate limits, latency variance, and output differences**.\n\n"
    
    "**Current Status:**\n"
    "- Core image generation is stable.\n"
    "- Advanced utilities are being rebuilt to work with the new backend.\n"
    "- Some tools may produce inconsistent results or temporary errors during this transition."
