  Modification (CPAL-1.0 §3.3), made by Relyt Works LLC in 2026: `citeproc.js` applies the
  `citeproc_commonjs.js` hunks of upstream pull request
  https://github.com/Juris-M/citeproc-js/pull/276 ("Cache sort-mode macro expansions to reduce
  memory usage", Dan Stillman, commit adffcfa3189ed21cbdb5272a74a8edbf817ac326) in
  `CSL.expandMacro`, `CSL.getMacroTarget`, and `CSL.configureMacro`. Macros used by sort keys are
  now expanded once into `state.sort_macros` and referenced, as ordinary macros already were,
  instead of being copied into every sort key; Chicago styles otherwise exceed the processor's
  memory limit. Drop this modification when upstream merges the pull request.
