Strip HTML tags

Removes HTML tags and leaves the text, turning block endings into line breaks so the result reads as paragraphs rather than as one run-on sentence.

The part naive tag-stripping gets wrong is script and style: removing only the tags leaves the JavaScript and CSS sitting in your output as text, which is both wrong and occasionally alarming. Their contents are removed entirely here. Block-level closings become line breaks so paragraphs survive, which a regex that simply deletes everything between angle brackets does not do. One thing worth knowing about security: stripping tags is not a sanitiser. If you are taking user HTML and putting it back into a page, you need an allowlist-based sanitiser, not a tag remover — the difference matters, and confusing them is a real vulnerability.
