in root.html). Outputs custom og:image with assets_prefix normalisation and non-Google site verification. --> penrose triangle | IT-Journey in _layouts/root.html. What this file adds: - Custom og:image with preview_images.assets_prefix path normalisation for the theme-specific page.preview and page.header.og_image keys. When page.image is set, jekyll-seo-tag handles og:image and this file skips its own og:image output to avoid duplicate tags. - Non-Google site verification tags (Bing, Yandex, Naver, Baidu) Dependencies: - jekyll-seo-tag plugin (loaded in _layouts/root.html via penrose triangle | IT-Journey ) - site.preview_images config in _config.yml =================================================================== --> penrose triangle | IT-Journey
