Bottom navigation bar

We can repurpose a MudToolBar for this (justify spacing between, remove spacer). MudTabs wouldn't work because we load everything as separate pages.

Highlighting is simple because each page can just highlight it's own icon.

Take a look the M3 Navigation bar for more resources.

Once we've proven it, we can consider backporting to MudBlazor.

Swipe

MudSwipeArea is possible but the transition won't look right since it's navigating to a new page. Unless there's a way of showing that as a transition?

MAUI

Another option for a more native feel is to handle this in MAUI. It's just not a pleasant development experience so I try and avoid it when possible.

MudBlazor also has the SwipeArea but I don't think it's quite fleshed out enough. Maybe some work on it could benefit us.
