# Hint Reveal

A "Show hint" disclosure button that expands to reveal help text. Built on the HTML details/summary element — no JavaScript required. The summary label toggles between "Show hint" and "Hide hint". Styled with a subtle left-border accent and muted background to visually separate it from body content.
