Banner

JSON-safe Banner props forwarded to Astryx.

Supported Astryx props include:

• status ('info' or 'warning' or 'error' or 'success'; required): Status type controlling icon and color.
• title (ReactNode; required): Title text or ReactNode displayed in the header.
• description (ReactNode): Description text rendered below the title in the header.
• icon (ReactNode): Override the default status icon.
• isDismissable (boolean): Whether the banner can be dismissed by the user.
• onDismiss (() => void): Called when the dismiss button is clicked; banner hides itself regardless of whether this is provided.
• endContent (ReactNode): Action content rendered in the header area, end-aligned. Typically a button or link.
• container ('card' or 'section'): Container type: card has border-radius; section is full-width with no border-radius for page-level use.
• children (ReactNode): Content rendered in the card-background area below the colored header.
• defaultIsExpanded (boolean): Whether the content area (children) starts expanded. Only relevant when children are provided.
• xstyle (StyleXStyles): StyleX styles for layout customization (margins, positioning, sizing). Must be a stylex.create() value, not an inline style object like style={{}}.

Props typed as React nodes, render functions, event handlers, refs, or StyleX styles are documented for Astryx parity but cannot be serialized directly from Python unless the wrapper adapts them.
