## Overview

Banners can help showcase special app experiences, new features, or important
messages. While functionally similar to standard rows, banners add distinct
visual prominence through customizable background fills and will always be
visually separated from surrounding content.

*** ** * ** ***

## Composition

The Banner item is designed for high glanceability and includes four components,
two of which are required:

- **Leading image or icon** (required)
- **Primary text: title and subtexts** (required)
- Secondary text (optional)
- Trailing image or icon (optional)

*2.* *Primary text*

## UX requirements

To ensure a safe and consistent experience across all apps, follow these design
requirements:

| Requirement level | Content |
|---|---|
| MUST | Display only one banner per section. Place banners in a dedicated section that contains no other component types. |
| SHOULD | Apply custom background fills, button accent colors, and distinct corner radii to separate banners from standard content rows. |
| SHOULD | Avoid placing banner sections directly adjacent to one another to preserve their visual prominence. |
