/**
 * Observes the size of a DOM element using ResizeObserver API and exposes
 * its current width and height.
 *
 * This hook enables container-driven responsive behavior, where layout
 * decisions are based on the actual rendered size of a component rather then
 * on viewport breakpoints.
 *
 * It was introduced to evaluate a container-based approach for responsive
 * layouts (e.g. in the Banner component), as an alternative to relying on
 * viewport-based media queries.
 *
 * @template T - The type of the observed HTML element.
 *
 * @returns An object containing:
 * - `ref`: a React ref to be attached to the element to observe.
 * - `size`: the current size of the element (`{ width, height }`),
 *   or `null` before the first measurement
