nx_math_render_page.nx

nx_math_render_page.nx -- GENERATE the live "/wiki/math_render.html" page (IMS Thrust D, rung 1): the VISIBLE proof of the sovereign "arXiv PDF->HTML / LaTeX" capability. A walkable Diataxis REFERENCE page built through the reusable typed generator nx_ims_page (full walk furniture: head/nav/breadcrumb/tree/prev-next/related/backlinks/infobox/toc/footer, nav read from wiki_links.tsv by slug=math_render). The page's OWN content (body_html) embeds REAL presentation MathML produced AT BUILD TIME by nx_tex (tx_render) -- the snippets are rendered, not hand-written: 1. the BM25 term-saturation factor f / (f + k) (the heart of the wiki's own ranker), 2. the full BM25 single-term score IDF * f(k1+1) / (f + k1(1 - b + b|D|/avgdl)), 3. the DLMF Gamma-function integral Gamma(z) = int_0^inf t^{z-1} e^{-t} dt, 4. a quadratic & the quadratic formula (msqrt + mfrac showcase), 5. a relations / greek line. Each formula is shown with its LaTeX source (escaped, in <code>) next to the rendered MathML, so a reader sees input -> output. ADDITIVE: writes web_assets/math_render.html only (the publish step pushes it live + fetch-verifies). REUSE (nothing reinvented): nx_ims_page ims_page (typed walkable generator) + nx_tex tx_render (the sovereign renderer). license_tier: ORIGINAL
