One ready-made excuse

Take this and vanish gracefully.

I am away for burnout leave while I rebuild my last functioning nerve while reality reorganizes my desk into folklore. Routine questions, follow-ups, and ordinary urgency can survive a short delay.

The pigeons have already reviewed the fallback plan.
