/**
* A declarative conditional rendering component that displays either children or fallback content
* based on a condition.
*
* @param {PropsWithChildren<ConditionProps>} props - Component properties
* @param {React.ReactNode} props.children - Content to display when the condition is truthy
* @param {unknown | ((props: any) => unknown | Promise<unknown>)} [props.when] - The condition or function that determines which content to show
* @param {boolean} [props.falsy] - When true, treats all falsy values (0, '', etc) as false conditions
* @param {React.ReactNode} [props.fallback] - Content to display when the condition is falsy
* @param {...unknown} props.rest - Additional props to pass to the rendered content via AsInstance
* @returns {Promise<JSX.Element>} Either the children or fallback content wrapped in AsInstance
*
* @example
* // Basic usage with fallback
* <Condition when={isLoggedIn} fallback={<LoginForm />}>
* <Dashboard />
* </Condition>
*
* @example
* // With function condition
* <Condition when={(props) => userService.hasPermission('admin')} fallback={<AccessDenied />}>
* <AdminPanel />
* </Condition>
*
* @example
* // With async function condition
* <Condition when={async () => await checkUserSubscription()} fallback={<SubscribePrompt />}>
* <PremiumContent />
* </Condition>
*
* @example
* // With falsy option to handle empty arrays
* <Condition when={results.length} falsy fallback={<NoResultsMessage />}>
* <ResultsList items={results} />
* </Condition>
*
* @example
* // Passing props to the rendered content
* <Condition when={hasPermission} fallback={<AccessDenied />} className="content-area">
* <AdminPanel />
* </Condition>
