+## Dependencies

+  - Update `dart-sass` to 1.107.1.
+  - Update `esbuild` to 0.28.2 (fixes a CSS minification bug involving `&` and a TypeScript import-alias tree-shaking bug).
+  - Update `typst-gather` to 0.2.4.
+  - Update `verapdf` to 1.30.3 (used by `quarto install verapdf` for PDF/A validation).
