Build me a polished web app called BannerCraft where someone can create marketing banners in seconds with AI. I want users to upload a product image, pick a color palette, theme, and a few design preferences, then have the app generate banner ideas and finished banner visuals automatically. It should feel fast and easy for a small business or marketer to use.

Please include a proper editor so people can tweak the result after generation, like changing text, moving elements around, drawing, adding shapes, watermarking, and doing simple image touchups. It would also be great to have a chat style helper that can suggest banner copy and simple sticker style visuals for quick personalization.

A big thing I care about is keeping the product image accurate and making sure text spelling is reliable, so use the original uploaded product image wherever needed instead of letting the AI distort it. Make the experience smooth and responsive, connect it to the backend repo if needed, and check the demo or docs online if anything is unclear.
