/**
 * StatusComponent - Root container for individual monitor/service status displays
 *
 * This component serves as the main container for displaying a single monitor or
 * service status. It establishes the status type context via data-variant attribute,
 * which child components (like StatusComponentIcon and StatusComponentStatus) use
 * to display the appropriate colors and icons.
 *
 * The component acts as a CSS group (/component) for advanced selector patterns,
 * enabling child components to style themselves based on the parent's variant.
 *
 * @param variant - The status type (success, degraded, error, or info)
 *
 * @example
 * ```tsx
 * <StatusComponent variant="success">
 *   <StatusComponentHeader>
 *     <StatusComponentHeaderLeft>
 *       <StatusComponentIcon />
 *       <StatusComponentTitle>API Server</StatusComponentTitle>
 *       <StatusComponentDescription>Main API endpoint</StatusComponentDescription>
 *     </StatusComponentHeaderLeft>
 *     <StatusComponentHeaderRight>
 *       <StatusComponentUptime>99.9%</StatusComponentUptime>
 *       <StatusComponentStatus />
 *     </StatusComponentHeaderRight>
 *   </StatusComponentHeader>
 *   <StatusComponentBody>
 *     <StatusBar data={uptimeData} />
 *   </StatusComponentBody>
