+# Workaround for a broken `minted` in nixpkgs.
+#
+# The TeX Live snapshot in nixpkgs (2026-03-01) predates minted 3.8.0
+# (2026-03-04) and still ships 3.7.0 together with a bundled `latexminted`
+# 0.6.0 that does not run. Two independent replacements are needed:
+#
+#   - the run container: minted.sty from the upstream 3.8.0 release, which
+#     requires `latexminted` >= 0.7.0;
+#   - the bin container: `pkgs.latexminted` (0.7.1), which works.
+#
+# The LaTeX package and the Python executable are versioned separately, hence
+# the two unrelated version numbers.
+#
+# Delete this file once nixpkgs ships minted >= 3.8.0.
