+# Leaving raw tty hides the shell's PROMPT and keeps the command typed at it.

+# The two share one grid row, so blanking the row used to take the command with
+# the prompt and a shell out of tty read as output only. OSC 133 marks the row
+# CELL by cell, so config.tty_blank = .prompt cuts the prompt's own columns and
+# left-hugs what is left: the command lands at column 0, in line with the
+# output under it, rather than in a bay of blanks the prompt used to fill.
+#
+# `.prompt_and_input` is the old behaviour and blanks the whole row; it is a
+# comptime choice, so what THIS script pins is the default.

+# The columns still have to reach the shell, and they do: the modal cursor's
+# column on a hidden-prompt row is short by exactly the prompt's width, so
+# enterTty adds it back before asking ghostty to walk the shell's own cursor
+# there. That arithmetic is pinned by the "entering tty walks the shell cursor"
+# unit test, which can put a pinned cursor on a known column; a click here
+# cannot, because leaving tty unpins and a body click on a terminal does not
+# pin it again.
