/**
 * Global state manager for chart configurations during streaming.
 * This singleton manages chart config state outside of the component tree,
 * preventing reactivity issues when charts complete during SSE streaming.
 *
 * The problem: When using render() from solid-js/web to mount ChartPlaceholder
 * components into DOM slots, the rendered components are in an isolated reactive
 * root that doesn't share the parent's reactive context. Props passed to these
 * components don't update reactively when the parent's signals change.
 *
 * The solution: Use a global manager with SolidJS signals that can be accessed
 * from any component, regardless of which reactive root it's in.
