📄 Description

Summary

Fixes EPUB rendering errors caused by non-XHTML compliant HTML tags in index.qmd.

Changes

Self-closed img tag for XHTML compliance
Added explicit value for controls attribute on audio element
Self-closed source tag for XHTML compliance
Changed content-visible condition from html to html:js to prevent HTML-specific interactive content from appearing in EPUB output

Testing

✅ EPUB builds successfully without XHTML parsing errors
✅ Pre-commit hooks pass

Closes #1014

Note

Updates quarto/index.qmd for EPUB-safe XHTML (self-closing tags, explicit audio controls) and restricts interactive HTML to html:js.

EPUB/XHTML compliance

Self-close img and source tags in quarto/index.qmd.

Use explicit controls="controls" on <audio>.

Rendering/visibility

Change content-visible condition from when-format="html" to when-format="html:js" for the abstract block to prevent interactive HTML from appearing in non-HTML outputs.
