Please create a horizontal 4:3, highly finished “AI Nail Inspiration Board” based on the user’s input [theme] or uploaded [reference image].

[Input Rules]
If the user provides a text theme, please perform abstract refinement based on the theme.
If the user provides a reference image:
- Image A is the inspiration reference image and the core inspiration source for this nail design plan;
- If the user also provides a hand photo, Image B is the hand reference image, used to help generate a real on-hand effect that is closer to the skin tone and hand shape;
- If there is no hand photo, please generate a group of natural, realistic, aesthetically pleasing general female hands wearing the nail design.

--------------------------------------------------
[Image Title and Subtitle]
The main title should clearly read:
AI Nail Inspiration Board

The English subtitle can read:
AI Nail Inspiration Board

The small title can be automatically generated according to the theme, for example:
Inspired by [theme name]
or
Visual Translation of [theme name]

If it is a Chinese theme, Chinese and English can also be combined, for example:
Inspiration Source / Inspired by [theme]
Concept Translation / Concept Translation

--------------------------------------------------
[Overall Layout Requirements]
Horizontal 4:3 layout, with an overall high-end proposal board composition.

The image is recommended to be divided into the following modules, while keeping the hierarchy clear, the whitespace comfortable, and the structure orderly:

1. Top title area
2. Inspiration source area
3. Visual element extraction area
4. 10-nail design area (core key visual)
5. Concept summary area
6. Recommended nail shape / finishes / scenario area
7. Actual on-hand preview area (very important)
8. Bottom summary area

Keep the background clean and restrained. Premium base colors such as warm white, cream white, light gray, light beige, and misty pink-gray can be used. Do not make it overly flashy.
The overall design feeling should lean toward high-end nail brand visuals, fashion magazine inner pages, and design proposal boards, rather than e-commerce detail pages or low-quality posters.

--------------------------------------------------
[Detailed Requirements for Each Section]

① Title Area / Title Area
Clearly present at the top of the image:
- Main title: AI Nail Inspiration Board
- English subtitle: AI Nail Inspiration Board
- Theme name: automatically generated according to user input
- A concise style description, for example:
“Extract colors, symbols, and emotions from the theme, and translate them into a complete wearable nail design plan.”

The title area should be concise and powerful, reflecting a high-end feel and a sense of design.

--------------------------------------------------
② Inspiration Source / Inspiration Source
If the user uploads a reference image, please display a thumbnail of the reference image in the upper-left or upper area and label it:
- Inspiration Source / Inspiration Source
- Theme name
- Brief description: what temperament and directions are extracted from the reference image for this design

If the user only inputs a text theme, present it in text form in this area:
- Theme name
- Theme introduction
- Core atmosphere description

This section should not be long text, but concise and professional, like a design note.

--------------------------------------------------
③ Visual Extraction / Visual Extraction
Please break down the inspiration into several clear small modules, with refined layout and clear information:

A. Color Palette / Color Palette
Please recommend:
- 3 main colors
- 2 supporting colors
- 1 accent color

Display them as small color cards and label the color names.
Color names can be more aesthetic, for example:
creamy apricot nude pink, cool silver gray, burgundy berry, ink green, haze purple, champagne gold, deep sea blue, pearl white, etc.

B. Style Keywords / Style Keywords
Extract 4–6 keywords, for example:
gentle, mysterious, vintage, cool beauty, dreamy, romantic, gorgeous, restrained, lightly sweet, futuristic, relaxed, cold and clean, dramatic, etc.

C. Motifs / Motifs
Extract 4–6 visual elements that can be translated onto the nail surface, for example:
moon, star trails, petals, water ripples, feathers, flames, ribbons, butterflies, plaid, book pages, musical notes, gold lines, vines, metallic frames, glass shard effect, etc.

D. Texture & Finish / Texture & Finish
Extract the craft directions suitable for this theme, for example:
cat eye, pearlescent, gold foil, gradient blooming, mirror finish, jelly translucency, French tips, shell fragments, matte finish, 3D water droplets, micro-relief, fine glitter, velvet feel, etc.

This whole area should look very much like a “design logic extraction board”, clear, professional, and concise.

--------------------------------------------------
④ 10-Nail Design Plan / 10-Nail Design Plan
This is the absolute core of the whole image and should occupy the greatest visual weight.

Please clearly display:
- 5 nails on the left hand
- 5 nails on the right hand

Each nail should be presented separately and clearly, with a concise description.
Each nail is recommended to include:
- Finger position (Thumb / Index / Middle / Ring / Pinky)
- Design name
- Short description (1 sentence)
- Main elements / finishes

The complete set of 10 nails must form a unified style while also having rhythmic variation. They cannot all be the same, and they cannot be unrelated and chaotic.
It should have both a complete series feeling and differences in details and layering.

--------------------------------------------------
⑤ Concept Summary / Concept Summary
Please create a small summary module on the right side or middle-right area, including:

- Style Theme / Style Theme
For example:
Midnight Rose / Midnight Rose
Sunset Coast / Sunset Coast
Retro Cinema Mood / Retro Cinema Mood
Spring Pages / Spring Pages
Ocean Starline / Ocean Starline

- Overall temperament description
Use 1 concise paragraph to summarize the direction of the whole plan, for example:
“This design uses low-saturation main colors, detailed metallic lines, and partial pearlescent finishes to translate the romance and restraint in the inspiration into a high-end nail design plan that is more suitable for daily wear.”

--------------------------------------------------
⑥ Nail Shape / Finishes / Suitable Scenario Area
Please make it into a small and refined module, including:

A. Recommended Nail Shape / Nail Shape
Automatically recommend 1–2 suitable nail shapes according to the theme and style, for example:
- Short round nails
- Squoval nails
- Oval nails
- Almond nails
- Medium-long oval nails

And briefly explain the reason, such as:
“looks more refined” “more suitable for daily wear” “better able to carry pattern layering” “makes the hands look more slender”.

B. Recommended Finishes / Recommended Finishes
Summarize the most important craft focuses of this design, for example:
gradient blooming, micro-pearlescence, gold line details, cat-eye flowing light, partial mirror finish, etc.

C. Best For / Best For
Explain suitable scenarios, for example:
commuting, dating, weddings, vacations, festivals, concerts, spring and summer, autumn and winter, etc.

This section should feel like “practical implementation advice”, enhancing the executability of the plan.

--------------------------------------------------
⑦ On-Hand Preview / On-Hand Preview
This part is very important and must be refined, realistic, and convincing.

Please generate a group of highly finished double-hand on-hand preview images, showing what this complete nail design truly looks like when worn on the hands.
Requirements:
- The hands are natural, realistic, and normally proportioned
- The hand posture is elegant, not exaggerated or stiff
- Nail details are clearly visible
- The lighting is soft and high-end, with a studio-shoot quality
- A natural posed photography style can be used

If the user provides a hand photo, please match its hand skin tone and basic hand shape features as much as possible;
If there is no hand photo, please generate a group of female hand effects that are friendly to general aesthetics, natural in temperament, and suitable for displaying nail art.

Key point:
This is not a simple small thumbnail, but a very critical implementation display module in the whole image.
It should make users feel at first glance: “This design can really be made, and it will look beautiful when finished.”

--------------------------------------------------
⑧ Bottom Summary / Final Note
Write a clear and powerful summary sentence at the bottom or lower-right corner, for example:

“This plan does not simply copy the inspiration source, but extracts its color, emotion, and symbolic language, translating it into a complete nail design that is more suitable for nail-surface expression while balancing beauty and wearability.”

This sentence should serve as a “closing + professional enhancement” element.

--------------------------------------------------

Finally, please output a horizontal 4:3, highly finished professional proposal image of “AI Nail Inspiration Board”.
Users should be attracted by this nail design plan at first glance, understand the whole design logic at second glance, and feel at third glance that this plan can truly be made and will look beautiful when finished.
