+## [Unreleased]
+
+### Changed
+
+- NPC reason answers now use role-specific dialogue contexts, so staff, guests,
+  delivery workers, performers and other archetypes answer instead of silently
+  deflecting the Reason verb.
+- Hollywood and the TV Studio now have door-staff lines for their wristband,
+  ticket, credential and guest-list checks.
+- Clarified the emergency radio cancellation message, the Ask verb in Help/HUD
+  hints, the start-menu key hint and the campaign-reset confirmation.
