# llimphi-widget-hero

Shared-element transitions, Flutter-Hero style.

The Llimphi runtime keeps a `HeroRegistry` retained between frames: if the same
`key` appears in a different rect across two consecutive frames, the runtime
interpolates `transform` so the node "flies" from the previous rect to the
current one. This widget is the canonical wrapper that marks the `child` as a
hero with the given `key` — an app composing with it never has to touch
`View::hero` by hand.

The previous signatures (`hero_view`, `hero_quick`) are kept so callers do not
break. They used to wrap only with `animated_inout` (fade); now they compose
`hero` + `animated_inout`, so a caller reusing the same `key` across routes gets
the real fly **and** the landing fade together.
