(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

Attribute “retina_logo_url” not allowed on element “img” at this point.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “img” at this point.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “main” role is unnecessary for element “main”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “contentinfo” role is unnecessary for element “footer”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “"” is not serializable as XML 1.0.
