Large "self-healing" (magnetic) privacy curtains for porch and outer doors wind-opening-resistance?

I have a porch that's a real pain in the butt in the way of privacy from the road. Would like to cover it, but I need to cover a 70 inch by 90 inch open entry.

I'd like to make it such that only a strip at about eye level for about 6-12 inches is transparent so that we can see through it, but everything else is shielded with at least a largely opaque or blurring plastic.  Would also be good to use a thick enough plastic that it would have some thermal barrier advantages to reduce temperature transfer when dogs are popping in and out of the front porch doggy door.

The goal here would be to have it "self-heal" with magnets in on the middle edges of the "curtains" and then magnets on the inside porch pillars to keep it open when we like or need to come in and out a lot. Would also be nice to be able to make it durable enough to withstand winds and use strong enough neodymium magnets that can hold through a stiff wind.

I've not found anything to kinda fit my needs so far online, but I was thinking I could build such a creature with some ingenuity...

I figured it would be good to try to get some input and thoughts here before I began this little adventure. Any thoughts or ideas?

We bought this:  https://smile.amazon.de/-/en/gp/product/B07PXQ2MNG/ a few years ago which might give you some ideas.  IIRC it was about 30 euros and has lasted 3 years with only a few annoyances.

Annoyances:
--It's attached to the door frame via adhesive on the back of a plastic clip, which clips the fabric into place.  When you go through too quickly or with something too large, it can pull out from the clip.
--The material is cheap plastic fabric and long cobwebby threads fray off the edges (without affecting the closure, just annoying)
--The magnets want to stick to anything metal near the frame:  shelving, fire extinguisher...

Your version would use different mounting and different fabric as your needs are different, I expect.  I actually don't think you want to use much stronger magnets - the design "wants" to fall into a closed position, and if your magnets are too strong it will risk tearing the fabric and add some real effort to going in and out.

Good luck!  It sounds like a fun project!

Oh, and regarding the 3rd annoyance above, I'd think hard about having magnets on your columns, as every time you go through the opening, the magnets in the center will swing wide and try to attach to the columns, instead of falling back into place.  If it's not an everyday thing that you need to hold it open, I'd attach physical ties to the curtain and columns.

This shower curtain see-through top.

I would suggest using the grommets to hang it from a shower rod or something similar and attach the magnets in several places as you have described.
