Please create a high-quality "Flavor Immersion Soda Hero Poster / Flavor Immersion Soda Hero Poster".

[User Input]
Flavor Theme: [Flavor Theme]
Packaging Type: [Packaging Type, such as slim can / standard can / glass bottle / retro glass soda bottle; if not filled, default to slim can]
Brand Name: [Brand Name; if not filled, auto-generated]
Product Name: [Product Name; if not filled, auto-generated based on theme]
Main Color: [Main Color; if not filled, auto-matched based on flavor theme]
Aspect Ratio: [Aspect Ratio, such as 4:5, 3:4, 1:1; if not filled, default to vertical 4:5]

Please generate a brand-level, high-quality, high-impact soda main visual poster based on the above information. The entire image must clearly represent a "soda / sparkling soda / carbonated soft drink" commercial advertising visual, not juice, milk tea, smoothie, heavy fruit drink, or ordinary still life photography.

[Overall Positioning]
This is not an ordinary product still life, nor a traditional flat poster, but a high-end brand main visual image centered around the flavor soda, with an immersive environment built around the corresponding flavor elements. The whole image should have a strong commercial photography feel, brand advertising feel, chilled freshness feel, and visual impact, suitable for new product promotion, brand posters, e-commerce lead images, social media covers, and advertising KV.

[Central Hero]
The central part of the image must feature a very prominent [Packaging Type] flavored soda product. The product should be placed along the central axis of the image, becoming the absolute visual core, complete, clear, refined, with a sense of volume and realistic texture. The packaging design should be premium, simple, and like a real existing commercial soda brand. The packaging must display the [Brand Name] and [Product Name], with minimal text but clear brand recognition. The product must be clearer, more prominent, and more present than the background and surrounding flavor elements.

[Flavor Immersive Environment]
Around the central soda product, build an immersive flavor environment highly related to the [Flavor Theme]. If it's a fruit flavor, use the corresponding fruit; if it's tea, floral, herbal, spice, or composite flavor themes, use real elements, ingredients, or imagery related to that flavor. They should be densely laid out and surround the central product, forming foreground, midground, and background layers to create a strong flavor atmosphere and visual envelopment. The elements should naturally connect, being rich but not chaotic, with the auxiliary atmosphere serving the soda subject and not overshadowing it.

[Soda Attribute Enhancement]
The visual identification of "soda" must be clearly emphasized, not an ordinary beverage. Please focus on showing:
- Chilled cold drink feel
- Fine and abundant condensation droplets
- Tiny carbonation bubbles / fizz
- Refreshing, transparent, slightly explosive feel
- Freshly taken from the refrigerator's icy cool state

The product surface must have high-quality, detailed droplets with realistic texture; mild cold fog, bubble, and splash effects can be added if necessary, but the overall effect should be restrained and not overly exaggerated.

[Photography and Composition]
Use the [Aspect Ratio] composition, preferably maintaining the main visual logic of vertical brand advertising. The overall composition is a centered hero composition, with the central product being the clearest, and the flavor elements forming spatial layers around it. There can be a small number of blurred foreground elements to enhance depth, the midground forms a clear wrap around the product, and the background is rich and full with natural transitions. Use high-end commercial photography language: shallow depth of field, macro details, realistic lens blur, transparent highlights, delicate reflections, professional studio lighting. The image should have extremely strong visual appeal.

[Color Strategy]
The overall color should revolve around the [Main Color], auto-matched based on the [Flavor Theme] if not specified. The color needs to be unified, vivid, memorable, and quickly convey the soda's flavor impression. Appropriate use of dark shadows, localized highlights, and a small amount of accent colors can enhance the layers, but they should not appear chaotic. The overall color should be rich, tempting, premium, and have brand texture.

[Style Direction]
The overall style should be:
premium, refreshing, immersive, bold, high-end commercial photography, soda brand key visual.
It should be stronger, more beautiful, and more complete than an ordinary product image, with strong visual impact while maintaining brand-level refinement and premium feel.

[Applicability]
The final effect should be like a real official soda brand main visual poster, directly usable for brand promotion, product promotion, social media covers, e-commerce lead images, and advertising displays.

[Avoid]
Do not generate an ordinary juice advertisement feel;
Do not weaken the central soda subject;
Do not let the fruit or ingredients overshadow the product;
Do not make it an illustration style, cheap poster style, or low-quality collage;
Do not include too much text, chaotic icons, or complex explanations;
Do not let the packaging be severely distorted or the text be too chaotic;
Do not miss condensation droplets, chilled feel, and the soda's carbonation bubble atmosphere.
