Create a detailed horizontal banner (800×500 ratio) for a Russian marketplace product card.
Show only the mouth area of a child, not the whole face. On the left side of the banner, show a close‑up of teeth after normal brushing: teeth look white, plaque is almost invisible, no colored areas. On the right side of the banner, show the same mouth after using a purple plaque‑indicator mouthwash: along the gum line and between the teeth there are thin, natural‑looking violet‑blue plaque traces, as if softly stained, not bright paint. The coloring must look realistic and not scary.
Place a realistic PLIND mouthwash bottle with purple liquid in the lower center.
Add Russian headline text at the top: «До — налёт не видно» above the left part, and «После PLIND — видно, что нужно дочистить» above the right part. Text must be sharp and readable.
Use my attached product photos and infographics as style reference: blue bottle with purple liquid, light violet and blue background, clean medical design. Keep the same color palette and overall mood, but create a completely new composition. Render all Russian text clearly and naturally.
