Tidy complains about the use of <menu> for no good reasons, it's too old for our purpose.

Use the official W3C HTML validator called Nu.
It's a Java Web Server, run it inside a Docker container.

aniram added this to the 2026.1 milestone

"Nu" outputs HTML, so create a layer on top of the HTML output that reads it line by line and outputs JSON containing a list of objects with:

error message
markup code
line number
template name
for each error.

Refactor our HTML Validator so that it can work with this JSON like it's a plugable interface, make it independent of the validator currently used. Any validation system that outputs JSON in the format defined above should work with our HTML Validator.

Also write some simple tests to check if the correct template name is displayed, error message, line number etc.
