This is a hacky way to add end-of-chapter bibliography sections to Typst. This feature is not natively supported (typst/typst#1097). The hack works as follows:

• The Typst document has a main bibliography that's invisible. All author-date citations get filled in normally by Typst.

• The Python script update-bibliographies.py uses typst query to pull in the list of citations in each chapter. These are passed to Pandoc to format based on a CSL file. Run this before compiling the Typst document. Using typst query is a bit tricky because we need both ref's and cite's, but cite's are not locatable. To get around this, cite is redefined to add metadata that is queried.

One huge drawback of this approach happens with conflicting citations in different chapters. If you have two (Smith, 2024) citations, one will be labeled 2024a, and the next will be labeled 2024b. That works if those references are cited in the same chapter and nowhere else. If they are in separate chapters, you'll get a 2024a in one and a 2024b in the second. The main workaround for this is manual entry of the citations.
