Claims (5)

1 . A vehicle cabin interior environmental control device comprising: a processor; and a memory coupled to the processor, the processor being configured to receive switching of a vehicle cabin interior environment, and to change the vehicle cabin interior environment by controlling at least a lighting device and an acoustic device, wherein the processor: carries out a predetermined start notification by controlling the lighting device and the acoustic device at a time of a start of changing of the vehicle cabin interior environment, and carries out a predetermined end notification by controlling the lighting device and the acoustic device at a time of an end of the changing of the vehicle cabin interior environment.
2 . The vehicle cabin interior environmental control device according to claim 1 , wherein: the vehicle cabin interior environment may be changed to correspond to one of a plurality of modes ; and in a case in which the processor receives, during execution of environmental change of a mode, switching of the mode of the vehicle cabin interior environment, the processor carries out the start notification, without carrying out the end notification.
3 . The vehicle cabin interior environmental control device according to claim 1 , wherein the vehicle cabin interior environment may be changed to correspond to one of a plurality of modes, only one type of the start notification is set, and only one type of the end notification is set.
4 . The vehicle cabin interior environmental control device according to claim 1 , wherein: the vehicle cabin interior environment may be changed to correspond to one of a plurality of modes, and a type of the start notification and a type of the end notification are set for each of the plurality of modes; the processor carries out the start notification of a type corresponding to a mode for which switching has been received; and the processor carries out the end notification of a type corresponding to the mode for which switching has been received.
5 . The vehicle cabin interior environmental control device according to claim 1 , wherein: in a case in which the processor changes the vehicle cabin interior environment by further controlling a seat device, the processor carries out control of a preliminary operation at the time of the start; and the processor provides notification, in the start notification, that control of a seat will start, in conjunction with control of the preliminary operation of the seat device.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2024-193976, filed on Nov. 5, 2024, the disclosure of which is incorporated by reference herein. BACKGROUND Technical Field The present disclosure relates to a vehicle cabin interior environmental control device. Related Art Japanese Patent Application Laid-Open (JP-A) No. 2022-041858 discloses technology for appropriately adjusting an environment of a vehicle cabin interior according to an atmosphere produced by plural occupants. JP-A No. 2022-041858 discloses a vehicle interior system that estimates an atmosphere of a vehicle cabin interior produced by plural occupants from sound detected by a sound detection section, and adjusts the environment of the vehicle cabin interior according to the estimated atmosphere. In the prior art, since rendering of an environmental change is executed without prior notice, there is a problem in that an occupant cannot easily grasp that the vehicle cabin interior environment has been switched and that the rendering of an environmental change is being executed. Similarly, there is a problem in that it is also difficult to grasp a switch to another environmental change or an end thereof. SUMMARY The present disclosure provides a vehicle cabin interior environmental control device that enables an occupant to easily grasp switching of a vehicle cabin interior environment. A vehicle cabin interior environmental control device according to a first aspect includes a processor and a memory coupled to the processor, the processor being configured to receive switching of a vehicle cabin interior environment, and to change the vehicle cabin interior environment by controlling at least a lighting device and an acoustic device, wherein the processor carries out a predetermined start notification by controlling the lighting device and the acoustic device at a time of a start of changing of the vehicle cabin interior environment, and carries out a predetermined end notification by controlling the lighting device and the acoustic device at a time of an end of the changing of the vehicle cabin interior environment. Due to notification of the start and the end in this manner, an occupant is made to easily grasp switching of the vehicle cabin interior environment. A vehicle cabin interior environmental control device according to a second aspect is the vehicle cabin interior environmental control device according to the first aspect, wherein: the vehicle cabin interior environment may be changed to correspond to one of plural modes; and in a case in which the processor receives, during execution of environmental change of a mode, switching of the mode of the vehicle cabin interior environment, the processor carries out the start notification, without carrying out the end notification. According to the vehicle cabin interior environmental control device according to the second aspect, switching of the environment can be smoothly carried out, and notification can be provided to the occupant. A vehicle cabin interior environmental control device according to a third aspect is the vehicle cabin interior environmental control device according to the first aspect, wherein the vehicle cabin interior environment may be changed to correspond to one of plural modes, only one type of the start notification is set, and only one type of the end notification is set. According to the vehicle cabin interior environmental control device according to the third aspect, by carrying out uniform types of the start notification and the end notification, the occupant can be made to easily recognize the start and the end of the environmental change. A vehicle cabin interior environmental control device according to a fourth aspect is the vehicle cabin interior environmental control device according to the first aspect, wherein: the vehicle cabin interior environment may be changed correspond to one of plural modes, and a type of the start notification and a type of the end notification are set for each of the plural modes; the processor carries out the start notification of a type corresponding to a mode for which switching has been received; and the processor carries out the end notification of a type corresponding to the mode for which switching has been received. According to the vehicle cabin interior environmental control device according to the fourth aspect, by carrying out types of the start notification and the end notification that have been set for each mode, the occupant can be made to easily distinguish what environmental change is being executed. A vehicle cabin interior environmental control device according to a fifth aspect is the vehicle cabin interior environmental control device according to the first aspect, wherein: in a case in which the processor changes the vehicle cabin interior environment by further controlling a seat device, the processor carries o
