Adding a property already in the Essential Graphics panel adds a mirror
(EgKind::Mirror: own name and place, one value in the comp and in every
instance; editing, reverting or pushing either acts on both). A property
control can also drive further properties of the comp (links follow the
main property both ways and take instance values). essential.addMirror,
essential.linkProperty, essential.unlinkProperty; panel badges and menu;
ExtendScript addToMotionGraphicsTemplate(As), canAddToMotionGraphicsTemplate,
motionGraphicsTemplateName, controller count/name and
exportAsMotionGraphicsTemplate.

Comps expose controls (properties typed as text/color/slider/checkbox/point/angle/dropdown,
Media Replacement, groups, comments); precomp layers get an Essential Properties group whose
edits override per instance (Push to Comp / Revert); templates export/import as an open ZIP
(manifest.json + project subset + media + poster). Stretched precomps keep protected regions
at their original speed.
