HtmlSanitizer

Uses AngleSharp to parse and manipulate HTML, protecting against tag poisoning and invalid HTML that could break layouts, as highlighted in the README for shielding from deliberate or accidental corruption.

Allows fine-grained control over allowed tags, attributes, CSS properties, and URI schemes, with extensive default lists provided, enabling customization for specific security needs.

The Sanitize() and SanitizeDocument() methods are safe for multi-threaded use on a pre-configured instance, facilitating performance in concurrent environments, as stated in the Thread Safety section.

Supports base URI configuration to resolve relative links and control allowed schemes, ensuring safe link management in sanitized content, with examples for adding schemes like 'mailto'.
