## Code

```php
// Template part slugs that may be used.
$wpide_allowed_parts = array( 'header', 'footer', 'sidebar', 'cta' );

add_shortcode( 'wpide_template_part', function ( $atts ) use ( $wpide_allowed_parts ) {
    static $depth = 0;

    $atts = shortcode_atts( array( 'slug' => '' ), $atts, 'wpide_template_part' );
    $slug = sanitize_key( $atts['slug'] );

    if ( ! $slug || ! in_array( $slug, $wpide_allowed_parts, true ) || $depth > 1 || ! function_exists( 'get_block_template' ) ) {
        return '';
    }

    $part = get_block_template( get_stylesheet() . '//' . $slug, 'wp_template_part' );

    if ( ! $part || empty( $part->content ) ) {
        return '';
    }

    $depth++;
    $html = do_blocks( $part->content );
    $depth--;

    return '<div class="wpide-template-part wpide-template-part-' . esc_attr( $slug ) . '">' . $html . '</div>';
} );
```

## Notes

Only slugs in the allowed list are rendered. Template parts must exist for the active theme (Appearance > Editor or the Patterns screen).
