Warning::
Missing or non-HTML5 doctype
The page is missing `<!DOCTYPE html>` (the HTML5 doctype) or uses a legacy HTML4 / XHTML doctype. Without the HTML5 doctype, browsers fall back to quirks mode for parts of CSS layout (`box-sizing`, `inline-block` baseline, table cell sizing), causing unpredictable rendering differences vs modern dev expectations. Add `<!DOCTYPE html>` as the very first line of the document.
