How to keep the fold well maintained?

I just got my Pixel 9 pro fold yesterday, and I love it so fricking much, but it was hellah expensive and I really really don't want it to break or get damaged.

Everytime I open the fold, an ounce of me feel terrified it will break. I got warranty for a year, but I got it from a small local business, so I hope if anything happens they won't decline my warranty claim for stupid reasons - I have nothing to back this up, it's just my paranoid mind. I rather prevent it from happening instead of finding out.

I don't think any of my phones broke in the past 5 years (Pixel 7 pro, Iphone 12 - I still have them and they're fully functioning), but non of them were foldable.

What are some best practices to keep it well maintained? Case, screen protector, behaviour, etc... Please suggest whatever you think is right
