lazy image

Updated the twig and modified to allow webp format logo

Google's tester (PageSpeed ​​Insights) also asks for the image size.

Image elements do not have an explicit width or height

It seems complicated to add it here, because the image format changes depending on whether you are on the desktop or on the mobile

Thanks for the proposal and patch. We attempted to apply the patch on DXPR Theme 6.0.2 via cweagans/composer-patches, but it fails with “Cannot apply patch …”, likely due to context/path changes (e.g., block--system-branding-block.html.twig, theme-settings.php). Separately, while serving images as WebP is beneficial, we don’t consider lazy-loading the site logo appropriate; the logo is part of the first paint/brand identity and should render eagerly (e.g., loading="eager" and possibly fetchpriority="high"). Our preference is to limit lazy loading to content images, not the branding logo.
