Type Alias: TransitionType

TransitionType = typeof TRANSITION_TYPES[number]

Base ECMA-376 slide-transition type (p:transition's single type child). Each maps to a <p:TYPE/> element; type-specific variants (e.g. direction) go in TransitionProps.variant. Modern PowerPoint-only transitions (Morph, Vortex, …) live in the p14/p15/p159 namespaces and are out of authoring scope for now. See docs/animations-and-transitions.md.
