## TL;DR
ARIA adds accessibility semantics when native HTML is not enough. It is powerful, but misuse can make interfaces less accessible.

## Core Explanation
ARIA roles, states, and properties help expose custom widgets to assistive technologies. Authors should still prefer semantic HTML controls when those controls already provide the needed behavior.

## Detailed Analysis
The repaired article cites the W3C ARIA specification, WAI authoring practices, and MDN guidance to keep claims precise and practical.
