ok its on the list

subproblems (im so dp-coded):

• store images in opfs
  • if you aren't using a modern browser that doesn't support opfs im sorry (im not sorry)
• eviction algorithm
  • this one is actually important because i dont want you to paste 300 pictures in a note then delete all the references but have the images still in storage for no reason
  • naive approach -> rescan the note when you open it and if a picture associated with the note isn't being used then delete it
  • honestly this is probably fine

yeah ill do it after i get sync working (or if i get stuck)
