 * React hook that generates runtime CSS for effective style targeting.

 * Each item in `effectiveStyles` maps a source selector (class or ID)
 * to target selectors, with its own `important` flag.
 * Injected `<style>` tags are auto-removed on unmount.
 *
 * @example
 *   useEffectiveStyle(widgetStyle);
 *   // {
 *   //   "effectiveStyles": [
 *   //     { "selector": "qo-font-md", "target": ".k-input,.k-picker", "important": true },
 *   //     { "selector": "#myWidget", "target": "span div .k-font" }
 *   //   ]
