Other / Validation / Language Check Bookmarklet

The Language Check bookmarklet reports the page's primary language and identifies elements with different language attributes. Extracts the `lang` attribute from the document element, finds all elements with their own `lang` attribute that are direct descendants (not nested inside other lang elements), and displays an alert showing the page language and a list of any element-level language declarations. Useful for verifying proper language markup when content changes languages.
