Motion Doctrine (Gateway)

Read this before composing any animation. It decides WHAT happens at every seam and how
every scene performs; the technique skills implement it. These rules supersede generic /
upstream motion guidance. The failure this prevents: scenes authored in isolation — the
eye's momentum dies at every cut, and scenes wobble in place between entry and exit.
