feat(deploy): halkyon.li's screen off after a minute without a key (ADR 0039, D20)
consoleblank=60 on the kernel's command line: the text console blanks and
amdgpu powers the iMac's panel down; a key wakes it.

# GRUB on the instance's host at home (ADR 0039, D20), as /etc/default/grub.d/halkyon.cfg:
# its menu shown for 5 seconds, so that at the iMac the way back (grub-dracut-fallback)
# can be chosen, and the boot in text, without a splash: no desktop, and the
# passphrase's prompt is plain on the screen as over SSH. The console blanks after
# 60 seconds without a key (consoleblank), which powers the panel down, backlight and
# all; a key wakes it, and the prompt at boot is shown until then.
