Japanese Ad Banner Grid Generator — 4-Panel Layout

Create a professional 2x2 grid of modern Japanese web banners for beverage, food delivery, cosmetics, and fitness industries with editable text fields.

This prompt is organized as structured JSON with fields such as type, layout, and panels. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.
