## TL;DR

ResizeObserver lets scripts observe element size changes. This repair removes overbroad claims and keeps to the W3C interface and MDN entry documentation.

## Core Explanation

ResizeObserver is useful when a component needs to react to its own rendered size instead of only viewport size. Observations are delivered as entries that identify the target element and expose the observed box sizes.
