class BlogPlugin implements Plugin
{
    public function getId(): string
    {
        return 'blog';
    }

    public function register(Panel $panel): void
    {
        $panel->resources([PostResource::class]);
    }

    public function boot(Panel $panel): void {}
}

$panel->plugin(new BlogPlugin);

register() runs as the panel is declared, and boot() once the app has booted.

The demo's sidebar card, palette button and login hint come from a plugin like this. For fields and columns, see forms plugins.
