Professionally ignore people with style.

This automated reply confirms I am unavailable, as previously implied by my calendar. I am conference-bound and temporarily loyal to a badge scanner. If this relates to approvals, deck revisions, or stakeholder choreography, it will wait. A response will happen later, because that is how absence works. For immediate needs, escalate through the normal chain before inventing a new one. Thank you for respecting the concept of unavailable.
