With allowed_tags empty, strips ALL HTML tags; script and style elements lose their CONTENT too, not just the tags. With allowed_tags set, disallowed tags are removed (their inner text kept) and allowed tags keep only attributes listed in allowed_attr -- an empty allowed_attr strips every attribute. Regex-based tag filtering, not a full HTML parser.
A typical wiring for sanitize html: value feeds the html pin; the value out pin feeds convert to uppercase.
