The rustdoc in this toolchain does not parse math (its pulldown-cmark options
omit ENABLE_MATH, `--mathjax` and `html_mathjax` are gone, and a `$$...$$`
paragraph is emitted verbatim). Display formulas were therefore written as
```text code blocks, which the request asked to replace with math syntax.
MathJax 3.2.2 (tex-svg-full, Apache-2.0) is vendored under
docs/vendor/mathjax so the rendered pages need no network access.
docs/mathjax.html loads it from the documentation root computed from rustdoc's
own static file prefix; crates/apsis-rs/build.rs copies it into that root, and
scripts/build-docs.sh makes the copy reliable. Each formula is wrapped in a
raw HTML `<div>` so the markdown layer leaves the LaTeX untouched, because
markdown would otherwise consume the backslashes in `\\\\`, `\,`, `\!` and
`\_`.
All 54 formula blocks (27 formulas, English and Chinese) become `$$...$$`;
the 22 command, 2 diagram and 2 scenario-format blocks stay as ```text.
The bilingual sweep had left some blocks with only their last paragraph
translated, a few with the Chinese inserted inside an English sentence,
and some with a repeated paragraph from a re-applied table. A rewrite of
the coverage checks found them; this fixes every block and restores the
comment separators that a cleanup pass had emptied.
A translation table for the sentences that recur across the error types
and the simple accessors let the same wording be applied everywhere at
once, which both keeps the Chinese consistent and covers a hundred and
twenty-nine sites in a single pass. Routing, topology, access and the radio
frequency crates are now part of the sweep.
