Integrate marked-footnote with the current marked renderer and DOMPurify allowlist. Preserve CSP, sanitize all generated HTML, support backreferences/accessibility, print cleanly, and theme through existing tokens. Performance budget: approximately 2.4 KB minified added asset and no parser migration.\n\nInspired by the lightweight workflow ideas in the sdkks/mdviewer fork. Thanks to @sdkks for the implementation input. Attribution belongs in issue/release records, not README or GitHub Pages.
