private fun downloadBackup(ctx: Context) {
    ctx.result(Files.readAllBytes(Path.of("/tmp/backup.zip")))
  }

also this piece - is this how static files are sent as well? Just read the bytes and send it as a result? or are there optimisations that you use when sending static files

it's pretty complex

but doing what you did should be fine too

i don't really want to "bless" application logic though
