# part of init — before the first interactive prompt — rather than being injected
# as keystrokes afterward. Keystroke injection raced the shell's init-time
# Device Attributes query (ConPTY answers DA1 with "\e[?62;4;9;22c" on stdin);
# when that response landed on the prompt alongside an injected "<cmd>\r" the two
# merged into a bogus executed line (e.g. "62;4;9;22ccls"). Running here avoids
# that entirely. Runs last so the prompt override / PSReadLine handlers exist.
