Who this affects
Screen reader users, especially in multilingual countries.
Why it matters
Without a language declaration the screen reader guesses, often reading Dutch or German content with an English voice, which is close to unintelligible. A one-line fix and a very visible failure in an audit.
How to fix it
Set <html lang="nl"> (or the correct code) on every page, including error pages.
