Feature Request: Layer Mask & Advanced Image Compositing for LumaBooth

Hi LumaBooth team!

I'd love to suggest adding a Layer Mask feature to the Layout Editor.

Currently, the layout options are quite limited when it comes to creative photo compositions. Having Layer Masks would allow us to crop, hide, and reveal specific parts of an image, creating more experimental effects like image slicing, overlapping portraits, and displacement compositions.

It would be even better if we could apply different masks to multiple copies of the same photo within a single layout.

I believe this feature would open up many more creative possibilities and give users greater flexibility in designing unique photobooth experiences.

I've attached a visual reference to better illustrate the idea. Would love to know if this is something your team could consider for future updates!
