v1.53.0

Fixed

• A wrong language picked at first start can be changed back. The Wi-Fi
  setup screen that follows the language choice now has a back arrow to the
  language list; there was no way back before. The arrow answers from the
  moment the screen appears: for almost a second after it was drawn, the
  device was starting its setup network and every touch was ignored.
• The account pairing screen fits on the screen. The instruction ran edge
  to edge, the address broke in two and the countdown was cut off at the
  bottom. The screen now has the same header as the Wi-Fi one, the address on
  a line of its own, the code under it and the countdown under that.
• The address under the QR is the one the QR points at. It read
  tigersystem.io/pair, which was written into the translations and answers
  404; it is now taken from the pairing link itself, so the two can never
  disagree again, and it is drawn at the largest size that fits it on one
  line. The pairing code is taken off it, whether the link carries it as a
  parameter or as the last part of the address, so the line is the address
  and nothing else.
• An empty printer list offers a button, not an instruction. It used to
  say "All printers hidden. Settings > Printers" and leave the rest to the
  reader; the home screen now carries a Select printers button that opens the
  picker.
• The printer lists no longer run off the screen. On the first-boot
  printer choice the Confirm button was sliced along the bottom bezel and the
  gauge clipped at the top; on the Settings printer list the last row was cut.
  Both lists were measured without the space the screen puts between its own
  rows.
• An expired pairing code returns to the sign-in choice by itself. It used
  to stop on an error screen that had to be tapped; a code nobody got to in
  ten minutes is not a failure, and choosing Google again fetches a fresh one.
• "Scan the QR code": a shorter instruction above the QR codes, in every
  language.
• The language list shows its scrollbar, like every other list - nine
  languages do not fit on one screen and nothing said there were more.
• The screen stays smooth when no NFC reader is connected. The device kept
  retrying the reader in a way that froze the interface for more than a second
  in every three - scrolling stuttered and a tap took a moment to land, which
  showed on first setup before the reader is wired.
