/**
 * Creates a reducer function for a specific application state that combines core and application-specific reducers.
 *
 * @template ApplicationSpecificState - The type of the application-specific state, must extend AppSharedState
 * @param appSpecificReducerMap - A Map containing application-specific action types and their corresponding reducer functions
 * @returns A reducer function compatible with React's useReducer hook that handles both core and application-specific state updates
 *
 * @example
 * ```typescript
 * const appReducers = new Map([
 *   ['CUSTOM_ACTION', (state, action) => ({ ...state, custom: action.payload })]
 * ]);
 * const reducer = reducerForSpecificApp(appReducers);
 * ```
 *
 * @remarks
 * The returned reducer handles:
 * - Core state actions (layers, places, periods, styles, etc.)
 * - Map-related actions (view changes, layer management, etc.)
 * - MapSet-related actions (sync, mode changes, etc.)
 * - Application-specific actions defined in the appSpecificReducerMap
 *
 * @throws {Error} When an unknown action type is dispatched
