/* One account, two devices.
 *
 * Everything here is written on one machine and read on another, and the parts
 * travel differently: a note's text is an encrypted column, a drawing is a
 * second one, and a PDF is a file the note only points at. That last is the one
 * worth proving — the bytes are uploaded once and fetched by id, so a device
 * that has never seen the document has to be able to ask the server for it.
 *
 * A second browser context is a second device: its own storage, its own cache,
 * its own session.
