How about gifting her an at-home escape room kit? There are a lot of options online that she could do from the comfort of her own home. Additionally, you could consider gifting her a puzzle or a mystery book that has an escape room-like plot or theme. Another idea is to give her a voucher for an in-person escape room experience once it's safe to do so.
Or you can get her a star map with an important date you share.
