+Pandoc 3.10's Typst writer backslash-escapes any metadata string starting with a
+literal dot (jgm/pandoc#11511, jgm/pandoc#11761). Quarto's `biblio.typ` partial
+interpolates the raw `bibliography` metadata value into `#bibliography(...)`, so a
+relative path with a leading dot (`./refs.bib`) previously compiled to invalid Typst
+(`path must not contain a backslash`). This document exercises that path directly.
+
+See @Cronbach_1951 for a citation that must still resolve correctly.
