Things changed in this dependency bump: Major version. Two real changes: the B64 markdown extension now restricts relative links to base_path by default (a behavior change, opt-out via restrict_path=False), and Python 3.9 support is dropped. Patch-level regex-efficiency fixes on top.

Components this dependency touches: Transitive only, pulled in by marimo (mlperf-edu uses marimo for its tutorial/notebook extra). Nothing in mlperf-edu's own code imports pymdown_extensions directly.

Downstream components that may break (if merged): Low risk. mlperf-edu/pyproject.toml already requires Python >=3.10, so the 3.9 drop is a non-issue. The B64 link-restriction change only matters if marimo's own markdown rendering uses that extension with relative links outside its base path, which isn't something mlperf-edu configures directly.

What to do before merging: Spot-check that marimo-rendered markdown (tutorial notebooks, if any ship images via relative links) still renders correctly after the bump.

Final decision: Let's get this merged.

CI is red here, but not because of this bump. The failing jobs (Tests, Audit, and Package Portability, and everything downstream of it) fail with ModuleNotFoundError: No module named 'matplotlib' in tests/test_paper_figures.py, matplotlib is imported by tools/generate_paper_figures.py but was never added to mlperf-edu/pyproject.toml or uv.lock. Same failure is hitting #2001, #1993, and #1992 right now, so this is repo-wide, not specific to this bump.

Once matplotlib is added as a dependency and this PR rebases onto that fix, CI should go green and this can be merged.
