+Additional reference supplied by Millie: https://www.youtube.com/watch?v=IUmUYHELJAY
+(21 seconds, inspected locally at two-second intervals on 2026-09-05).
+The clip shows the player's ship approaching the Almighty, a view along its exterior weapon
+structure, and a fade to black. Millie specifies the sequence as ordinary fly-in, then this
+cinematic, then player spawn. The clip itself ends before the player spawn.
+
+The controller selects authored cinematic state 49 and its type-6 bookend slot, then selects
+playable state 64 only on that slot's termination event. Early region-64 reports cannot start
+landing combat or guidance before that handoff. No 21-second timer is used: completion/skip
+comes from the cinematic event. The selected package asset and the absence of a premature
+player spawn still need visual confirmation in the running game.
