Add to wp-config.php:

define( 'DISALLOW_FILE_MODS', true );

Useful when managing plugin updates via Composer.

<?php
the_post_thumbnail( '', array( 'loading' => 'eager' ) );

<div class="blog-navigation"><?php posts_nav_link( ' ', 'Previous', 'Next' ); ?></div>

.blog-navigation {
	display: flex;
	justify-content: flex-start;
	padding: 1rem 0;

	a {
		@extend .button;
		@extend .button--primary;
	}

	// Ensures Next button is always right aligned, even when no Previous button
	a:last-of-type {
		margin-left: auto;
	}
}

Otherwise it falls back to echoing another menu (the first?) instead of nothing.

<?= wp_nav_menu( [ 'echo' => false, 'fallback_cb' => false, 'theme_location' => 'footer-2-a' ] ) ?: ''; ?>

<?php

$args = [ 'show_in_rest' => true ];

register_post_type( 'post-type-slug', $args );
