Math fences (math/tex/latex/katex) consult the ZaTeX subset engine, loaded as a dynamic plugin outside the size budget; subset-accepted fences are native-eligible (display arm: read#348), everything else keeps today's code-card fallback byte-identical. An absent dylib is a clean fallback, so CI without a sibling checkout stays green. - src/core/math_fence.zig: dlopen loader (loadFrom/loadDefault/ close, twin-stubbed), subset consult (classify), token mapping. - docs/plugins-async-spec.md: external KaTeX/MathJax rows marked SUPERSEDED in favor of the native direction. - No viewport behavior change; no build.zig.zon change (runtime loading keeps the build hermetic). Verified: strict gate 497/497 (ReleaseFast, incl. 4 new tests with live-engine consult), size gate PASS (core 154174/204800, plugin 5700/12288).

Native math direction per zatex#12 (that issue tracks the cross-repo work): math fences consult the ZaTeX subset engine, loaded as a dynamic plugin outside the size budget. Subset-accepted fences are native-eligible (display arm: read#348); everything else keeps today's code-card fallback byte-identical. Absent dylib is a clean fallback.
Verified locally: strict gate 497/497 ReleaseFast (incl. 4 new tests, live-engine consult proven), size gate PASS (core 154174/204800, plugin 5700/12288).
