// T-WarningLead notification and the T-FinalWarningLead fallback dialog live
// in the desktop UI), so linking the full sessionwatch package (timers, event
// composition) would only bloat the binary.

// It still mirrors the deadline into the status recorder so the SubscribeStatus
// / Status snapshot the UI consumes stays correct — only the timer-driven
// warnings are dropped.
