[Feature] Option to cycle back to random photos after showing today's memories (instead of looping memories)

I have searched the existing feature requests to make sure this is not a duplicate request.

The feature

Currently, when memories are enabled, the kiosk seems to loop through today's memories indefinitely once they reach the end, without returning to the regular/random photo stream.

I would like an option (e.g. via an environment variable / config toggle) to control what happens after all memories for the day have been displayed:

Current/Default behavior: Loop today's memories continuously.

Proposed option: Play today's memories once, and once the list is finished, seamlessly fall back to displaying random photos for the rest of the day (until new memories are available the next day).

Additional context
Adding a toggle (like MEMORIES_LOOP=false or FALLBACK_TO_RANDOM_AFTER_MEMORIES=true) to the Docker configuration / environment variables would keep the kiosk dynamic while still highlighting daily memories.
