The renderer wires KaTeX via initMathSupport() and calls
window.renderMathInElement(...) inside _renderPreview() — there were no
tests pinning any of that contract. This commit adds tests/math-rendering.test.js:
- inline ($, escaped \() and display ($$, escaped \[) delimiters all
render valid TeX
- mixed prose + math preserves siblings (headings, lists, etc.)
- invalid LaTeX degrades gracefully under default throwOnError:false, so
the renderer's outer try/catch contract stays load-bearing
- dollar-heavy prose doesn't throw (the renderer's auto-render call must
be robust to anything in the doc)
- bundle wiring: katex.render() and renderMathInElement are exported,
katex.min.css ships in assets/, and index.html references it without a
CDN (the old jsdelivr link was removed in a prior hardening pass)
