#

# Austere on purpose. A real phosphor terminal had no decoration: one hue, one

# line, a block cursor. The only colour that is not green is the amber chevron,

# and it is amber for the same reason the scheme's alarm slots are -- a

# monochrome tube could not paint a warning in red, so the machines that needed

# two states used two phosphors.

#

# function global:prompt so the binding sticks when dot-sourced from inside

# tstyles.ps1's Invoke-TerminalStyle.
