/* HandyCafe changelog page. Scoped under .hccl so the shared header, footer
 * and Tailwind utilities on the rest of the page are left alone. Dark mode
 * follows the site's own `html.dark` class, which header.php sets from the
 * stored preference or the OS setting, so this page never disagrees with the
 * theme toggle in the navbar. */
