Trust me on this: do a simple phone capture (photos) as immediately as possible. We always delay things, and then they get lost irrevocably - in fire, flood, during the move, accidentally destroyed. Do plan doing the "capture proper", but do this simple one ASAP - it could take 15-30-60 minutes, but at least you'd have some sort of a backup.
Unfortunately, I am speaking from experience: just recently, I discovered that many years of my own notes were quite water damaged by a leaky pipe I wasn't even aware was there... and the slowly dripping water found its way to it through and over a random maze of random things worthy of the Rube Goldberg himself.
