The `useEditor` hook must be used inside the <Slate> compone

Error message

The `useEditor` hook must be used inside the <Slate> component's context.

What it means

useEditor() requires the React context provided by <Slate>. Calling it in a component rendered outside a <Slate> provider yields a null context, and the hook throws to surface the mistake early instead of returning undefined and crashing later.

Solutions

1. Move the component inside the <Slate>...</Slate> subtree
2. In tests, wrap rendered components in a <Slate editor={editor} initialValue={...}> helper
3. For portals, wrap portal content in the same context provider or use a custom render target inside the tree

Example fix

// before
function Toolbar(){ const editor = useEditor(); ... }
render(<Toolbar/>) // no provider

// after
render(
  <Slate editor={editor} initialValue={initialValue}>
    <Toolbar/>
  </Slate>
)

// render helper
function renderWithSlate(ui) {
  const editor = withReact(createEditor())
  return render(<Slate editor={editor} initialValue={[{type:'paragraph',children:[{text:''}]}]}>{ui}</Slate>)
}

When it happens

Trigger: Calling useEditor() (or a component that uses it) outside of <Slate>...</Slate>; rendering editor-dependent components as siblings rather than children of <Slate>; testing components with render() but no Slate wrapper; portals rendered outside the provider tree.

Common situations: Component trees reorganized so a leaf ends up outside <Slate>; unit tests (Jest/RTL) rendering leaves without the provider; portals to document.body escaping the context.
