(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.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “div” at this point.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “_blank"_parent"” for attribute “target” on element “a”: Reserved keyword “blank"_parent"” used.
No “p” element in scope but a “p” end tag seen.
Warnings:
The “banner” role is unnecessary for element “header”.
