Widget (FS-Skia-UI)

Widget Module

The typed-tree lowering bridge: `ofControl`/`toControl` convert to and from the legacy IR, and `render` paints a `Widget<'msg>`.

Function or value	Description
`map f widget` Full Usage: `map f widget` Parameters: f : `'a -> 'b` widget : `Widget<'a>` Returns: `Widget<'b>` Type parameters: 'a, 'b	Feature 108 (US5, FR-014): `Widget.map f = ofControl ∘ Control.map f ∘ toControl` — change only the message type of the lowered control, preserving structure / key / focus identity. f : `'a -> 'b` widget : `Widget<'a>` Returns: `Widget<'b>`
`ofControl control` Full Usage: `ofControl control` Parameters: control : `Control<'msg>` Returns: `Widget<'msg>` Type parameters: 'msg	Migration bridge: lift a legacy `Control<'msg>` into the typed tree (e.g. to drop it into a typed `Stack.Children`). FR-002. control : `Control<'msg>` Returns: `Widget<'msg>`
`render theme widget` Full Usage: `render theme widget` Parameters: theme : `Theme` widget : `Widget<'msg>` Returns: `ControlRenderResult<'msg>` Type parameters: 'msg	Convenience = `Control.render theme (toControl widget)`. FR-009. theme : `Theme` widget : `Widget<'msg>` Returns: `ControlRenderResult<'msg>`
`toControl widget` Full Usage: `toControl widget` Parameters: widget : `Widget<'msg>` Returns: `Control<'msg>` Type parameters: 'msg	Lowering accessor — the single, explicit seam to the existing IR. Used by render and the Elmish adapter. FR-002. Invariant: toControl (ofControl c) = c. widget : `Widget<'msg>` Returns: `Control<'msg>`
