/**

 * keyed by `id`, syncs the consumer props (`data`, `isLoading`, `error`,
 * `formatter`, …) onto it, and exposes the `id` via `WidgetContext` so
 * descendants can resolve their store with `useWidgetId()`.
 *
 * The Provider deliberately doesn't know about ECharts — there's no
 * `optionFactory` prop here. ECharts-backed widgets pass their factory
 * to `<Widget.Echart optionFactory={…}>`, which owns the structural
 * seed + the data-fusion render step entirely. Non-Echart widgets
 * (Formula, Spread, Range, Table, Category, Markdown) just don't pass
 * anything ECharts-shaped.
