micromark HTML Tag Names Utility

micromark-util-html-tag-name is a low-level utility package within the `micromark` ecosystem, providing curated lists of HTML tag names relevant for CommonMark-compliant Markdown parsing. Specifically, it exports `htmlBlockNames` and `htmlRawNames`, which are used by `micromark` to apply specific parsing rules for HTML (flow) constructs. The `htmlBlockNames` array aids in determining when more relaxed parsing rules apply, based on CommonMark's condition 6, while `htmlRawNames` guides the parser on when HTML content can include lines without exiting until a matching closing tag is found (CommonMark's condition 1). This package is currently in its stable version 2.0.1 and is actively maintained as part of the `micromark` monorepo, which generally sees frequent updates, often with performance enhancements, and drops support for unmaintained Node.js versions with new major releases. It's designed for developers building or extending `micromark` itself, rather than for general HTML tag lookup.
