/**
 * @brief A template class that encapsulates a fixed, compile-time constant value.
 *
 * @tparam T The type of the value.
 * @tparam Value The fixed value of type T.
 *
 * This class provides a way to encapsulate a value that is constant and known at compile-time.
 * The value is stored as a private member and cannot be changed. Any attempt to assign a new
 * value to an object of this class will reset it to the fixed value.
