Generate your online store's banner with AI

Act as a graphic designer specialized in hero banners for online stores (e-commerce).

Here's my store's context:

- What I sell: [E.G. HANDMADE CANDLES, ATHLETIC WEAR, HANDCRAFTED JEWELRY]
- Product or collection to feature: [DESCRIBE OR ATTACH THE PRODUCT]
- My brand's color palette: [E.G. EARTH TONES AND GOLD, PASTEL AND WHITE, BLACK AND NEON]
- Banner message or promotion (if any): [E.G. NEW COLLECTION, FREE SHIPPING, 20% OFF, or NONE]
- Visual style: [E.G. MINIMALIST AND CLEAN, WARM AND HANDMADE, MODERN AND BOLD]
- Where the banner goes: [E.G. HOMEPAGE HERO, TOP OF A COLLECTION PAGE, INSTAGRAM BANNER]

Generate the banner with:
1. Horizontal hero-style composition, with clear negative space on one side to fit a headline and a "Shop now" button (don't add that text yourself, just leave the space).
2. The product or scene as the main subject, with lighting and colors that match the brand palette I gave.
3. A background or setting that reinforces the requested visual style, without overwhelming or competing with the product.
4. Clean, professional composition, at the level of a real online store, not a casual photo.

Don't invent text, logos or prices I didn't give you. If I didn't specify a banner message or promotion, don't make one up: leave the banner without text.
