Accounting for wood movement in a headboard?

Thanks Peter! The bed is complete, just need to order some new sheets to get some glamour shots of it!

I joined the headboard with the exact domino technique you recommend with the glued joint in the center of the panel...I could've done it at the top of the panel, but clamping this up was quite the feat with it being 80inches wide and felt it would be easier to do in the center.

Here's a photo of the mortises in the head post:

I know this is an old post but I was wondering if you had the angles for those legs. I’m building a bench and I think they would look great.
