Dismounting hands back the exact view you left

Stepping out of a creature's skull treated the return as a fresh cut,
and fresh cuts face the deepest corridor — spinning the rider 90
degrees from where they had been looking. The saddle now remembers:
your position and facing are saved at mount and restored verbatim on
every dismount path (the button, the turn passing, the mount dying),
with no cut and no re-aim.
