TeXLayout.jl - possible successor to MathTeXEngine.jl?

I wanted to let you know about a new package I've been working on (rather, that I've been getting Claude to work on): [TeXLayout.jl](https://github.com/dawbarton/TeXLayout.jl), an OpenType-aware LaTeX math typesetter for Makie.

I started from MathTeXEngine but fairly quickly concluded that achieving what I was after would require rewriting essentially all of it. So a new package made more sense than a PR. The main differences:

- Layout constants come entirely from the font's OpenType MATH table (no hard-coded fallbacks), so metrics are always consistent with the font in use.
- Any OpenType Math font works out of the box; eight families (New Computer Modern, STIX Two, Fira Math, TeX Gyre variants, Luciole) are bundled as lazily-downloaded Julia Artifacts — zero configuration for end users.
- Full TeX style cascade (D/T/S/SS with cramped variants), correct inter-atom spacing, italic correction, auto-sized delimiters, matrices, horizontal braces, `\boldsymbol`, and more.

It integrates with Makie via a package extension that intercepts `generate_tex_elements(::LaTeXString)`, so existing Makie code works without changes (but type piracy abounds - I'd want to fix this if possible).

It's still early days with the code, but it's got pretty good TeX math coverage. I still need to wire up quite a few bits and pieces (including CI...).

I wanted to ask what you think makes most sense going forward. A few options as I see them:

1. **Deprecate MathTeXEngine** in favour of TeXLayout
2. **Fold TeXLayout into MathTeXEngine** — replace the layout engine under the existing package name.
3. **Maintain both** independently
4. Something else entirely?

No pressure at all, happy to discuss. (I haven't registered this package yet as I wanted to get your thoughts before doing that.)
