use function App\Shared\Helpers\cms_head;
?>
<!doctype html>
<html lang="<?=Devflow::$PHP->configContainer->string('app.language');?>">
<head>
    <meta charset="<?=Devflow::$PHP->configContainer->string('app.charset');?>">
    <?php cms_head(); ?>
</head>

<body>
    <?php cms_body_open(); ?>

    ...

Custom SEO Routes

Custom SEO Routes allow you to define search engine metadata and structured data for routes that are not managed by Devflow CMS Pages, Content, Products, or by using a theme.

When a visitor requests a matching route, the defined metadata and schema automatically gets injected into the page.
