Summary:\n\n**Answer**: MathJax 3.2.2 (vendored, no CDN) — and it was never broken. The research archive writes math in **plain Unicode notation** (`|r(w)| ≤ 1.2/|w|²`), not LaTeX, so MathJax had nothing to typeset outside the Resources Atlas (which does contain real LaTeX and renders fine).\n\n**Fix applied** (typography pass, website-only):\n- `render_markdown` now lifts the archive's two-space-indented display formulas into styled blocks — detection uses the archive's own convention (colon lead-in + math-signal characters, chained `+`/`−` aligned continuations), so wrapped prose stays inline. **174 display blocks** lifted, verified zero false-conversions and zero broken code blocks across all collections.\n- `.math-line` blocks styled with Cambria Math / STIX Two / Segoe UI Symbol at 16px with preserved alignment spacing; body text gained a symbol fallback font.\n- Content is never modified — lines are HTML-escaped and restyled only.\n\n**Verified live**: 20 routes OK, D-056/R-003/D-026 (the heaviest math files) render clean formula blocks, resources LaTeX pages untouched.\n\nCommitted as `bf7af04` (only `web/` + `RH-WEBSITE.md`, per the §0 rule). **Hard-refresh your browser** (Ctrl+F5) to pick up the new CSS.\n\nIf you later want true typeset equations on the archive pages, that's the full LaTeX conversion route — a research-side decision for a future session."}]
