Solid work here! Lots of comments but mostly just trying to sync up on some of the standards/practices that we have in cauldron. There's some additional comments from @bobbyomari

Some notes:

• There is a 4px gap at the top and bottom - is there a way to remove that so the gap and make the elements inside the popover set the spacing (the popover doesn't define the spacing between elements)
• I think the min-height should be removed or set to auto so that the height can just form to the contents inside?
• Set the close button to be secondary button and flip the positions so Apply is first
• spacing between the text and the button should be 8px
• spacing between both buttons should be 8px

This is really close, just a few nits and one last thought.

With role="dialog" we also need to ensure we're setting aria-hidden correctly on elements outside of the popover. For Dialog, we have a utility for that (see example) that we could pull in here.

Last couple of things! We should be ready to go once we get these few things addressed.

This one is almost good to go! Just need to fix the merge conflict and looks like the layout of the prompt popover doesn't match the design now:

@orest-s If everything is good here, feel free to squash and merge when you're ready.
