[dependabot]

Bumps quantecon-book-theme from 0.20.0 to 0.20.3.

Release notes

Sourced from quantecon-book-theme's releases.

v0.20.3

Fix h5 heading size hierarchy

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)

v0.20.2

Fix emphasis color on textual citation "et al." text

Fixed

• Emphasis color on "et al." in textual citations (#378) — the v0.20.1 fix only targeted <em> inside <a class="reference"> links. With bibtex_reference_style: author_year, sphinxcontrib-bibtex places <em>et al.</em> as a sibling of the link, not a child. Added span:has(> a.reference) > em CSS selector to handle this structure across all theme variants (light, dark, gruvbox).

v0.20.1

Fix emphasis color on citation reference links

Fixed

• Emphasis color applied to "et al." in citation links (#366) — added a.reference em CSS overrides so <em> tags inside sphinxcontrib-bibtex citation reference links inherit color and font-weight from the parent anchor instead of the theme's emphasis styling. Applied across light, dark, and gruvbox color schemes.

Changed

• Relaxed sphinxcontrib-bibtex upper bound (#366) — updated docs dependency from <=2.5.0 to <3, allowing compatibility with the 2.6.x series (latest 2.6.5).

CI

• Bump codecov/codecov-action from 5.5.2 to 6.0.0 (#377)
• Bump actions/deploy-pages from 4 to 5 (#376)
