/**
 * PopoverContent Component
 *
 * A composable component for the popover content panel.
 * Renders in a portal with collision detection and animations.
 *
 * @public
 *
 * @example
 * ```tsx
 * <Popover>
 *   <PopoverTrigger>
 *     <Button>Open</Button>
 *   </PopoverTrigger>
 *   <PopoverContent side="bottom" align="center">
 *     <p>Content goes here</p>
 *   </PopoverContent>
 * </Popover>
 * ```
 *
 * @remarks
 * - Renders inside a portal to avoid overflow clipping.
 * - Uses Radix collision detection to stay within the viewport.
 * - Supports `asChild` prop to merge props with a custom child element.
 * - Animated with fade, zoom, and slide transitions.
