billscroll: first log entry on a fresh room is a system-authored Welcome to <name>! greeting — epic.create_room records a ROOM_CREATED GameEvent (actor=None) immediately after Room.objects.create(...) so every room's scroll opens w. the greeting before any user action; GameEvent.to_prose ROOM_CREATED branch swapped from the unused "opens this room" legacy prose (verb was declared since the initial drama-app spike but no view recorded it — only test fixtures + AP federation tests touched it) → f"Welcome to {self.room.name}!", deliberately dropping the actor prefix the rest of the verbs lead w. since the welcome is the room's greeting, not a user action; scroll template (templates/core/_partials/_scroll.html + templates/apps/billboard/_partials/_applet-most-recent-scroll.html) gain an event.actor-guarded <strong> so the welcome line renders w.o. a leading empty <strong></strong> whitespace gap, and the .drama-event class branches now read mine / theirs / system (the new system slot replaces the prior else: theirs fallthrough when actor is None, opening room for system-line styling later w.o. mis-attributing the welcome to a phantom player); RoomCreationViewTest gains test_create_room_records_welcome_event_with_no_actor + test_create_room_welcome_event_renders_welcome_prose; the existing drama.tests.integrated.test_models tests (test_record_without_actor + test_events_ordered_by_timestamp) already exercise actor=None on ROOM_CREATED + the chronological-first position so the rendering contract holds; 928 ITs green — TDD
