+### Fixed
+- **h5 headings appearing larger than h4** (#381) — `h5` had no dedicated CSS rule, so it inherited the browser default size and "PT Serif" (a visually larger serif font) while `h4` used the more compact "Source Sans Pro" at `1.2rem`. Added explicit `h5` styling (`1rem`, Source Sans Pro, weight 900) to restore the correct heading size hierarchy.

+### CI
+- Bump `actions/github-script` from 8 to 9 (#380)
+- Bump `pypa/gh-action-pypi-publish` from 1.13.0 to 1.14.0 (#379)
