// NOTE: posting to `.cgSessionEventTap` collides with HotkeyMonitor's
// own listen-only tap, which is installed at `.headInsertEventTap` on
// that same `.cgSessionEventTap` location — the synthetic keystrokes
// get silently swallowed before reaching the focused app. Posting to
// `.cgAnnotatedSessionEventTap` (further down the pipeline, past that
// tap) delivers reliably. Confirmed empirically: cghidEventTap and
// cgSessionEventTap both silently no-op here; cgAnnotatedSessionEventTap
// lands in the focused text field every time.
