the archive demo kit

whats in here:
  assets/          five images. upload all of them in the Assets tab (part 3
                   tells you when). bg_* are backgrounds, mara and archivist
                   are the two characters.
  finished.json    the complete demo. ONLY open this if you are stuck: in the
                   creator, Files tab, Open a file. it replaces whats on your
                   screen, so save your attempt first if you want to keep it.

what each image is:
  bg_library.svg   the archive shelves. first thing the player sees.
  bg_door.svg      the sealed door with the word-slot.
  bg_passage.svg   the lit passage behind the door. the payoff shot.
  mara.svg         mara. make her a Character preset: center stage, scale 0.6.
  archivist.svg    the archivist. also a Character preset: left side, scale 0.5, hides later.

thats it. part 3 of the tutorial walks you through the rest.
