How can I safely clean crumbs from my MacBook Air M3 keyboard?

I have a MacBook Air M3 and I've noticed a significant accumulation of crumbs and small debris lodged underneath the keys of the keyboard. I'm really concerned about potentially damaging the sensitive internal components or the keys themselves if I try to clean it incorrectly. Given the modern, low-profile design of these keyboards, I know they can be quite delicate.

Could you please provide a detailed guide on the safest and most effective methods to remove these crumbs? I'm looking for advice on specific tools, techniques, and any precautions I should absolutely take to avoid causing scratches, dislodging keys, or affecting the keyboard's functionality. I want to make sure I'm not overlooking anything crucial that could lead to a costly repair.
