shortcode template to HTML-escape example.name using md.utils.escapeHtml before
inserting it into the quoted attribute. Keep the existing label format and all
other template output unchanged.

This allows a pre/code element to be slotted instead of a template tag. This helps when the code content is automatically wrapped by 11ty and reduced duplicative code blocks in the output source.

generation to HTML-encode codeblockLanguage with markdown.utils.escapeHtml
before inserting it into the quoted language attribute. Preserve the
javascript-to-typescript alias while ensuring fallback fence tokens cannot
inject attributes or markup.

- Around line 46-49: Update the marker generation and restoration logic in the
transform function to prevent collisions with ordinary document text: scope
markers to each invocation using a unique per-run prefix, and ensure restoration
matches only markers created during that invocation. Preserve JSON-LD and
template protection behavior while avoiding replacement with unrelated or

Escape codeblockLanguage before inserting it into the HTML attribute. The registered markdown-it fence rule takes the first token.info field and passes it to highlight. A quote in that field reaches language="${codeblockLanguage}" unescaped and can produce malformed markup or unintended attribute parsing. Use markdown.utils.escapeHtml(codeblockLanguage) for this attribute value.
