//! Tectonic engine prototype (M-tectonic): `cargo feature tectonic`,
//! OFF by default so wheels stay lean and TinyTeX/pdfTeX stays the
//! default (arXiv-closest). Tectonic embeds XeTeX + a cached bundle:
//! no TeX install needed, at the cost of snapshot drift from arXiv's
//! TeX Live and first-run bundle downloads.
//!
//! XeTeX is UTF-8 native: feeds MUST drop `\usepackage[utf8]{inputenc}`
//! (Python `tex_for_tectonic` does this). Everything else is standard
//! LaTeX; bundle gaps (e.g. publisher classes) surface as engine
//! errors naming the missing file — prototype-grade diagnostics.
