DOC: `make html ..` warnings (errors) on latest `main` (intersphinx broken?)

[tylerjereddy]

Working locally (MacOS ARM, Python 3.14, Sphinx v9.1.0) on latest main branch at the time of writing:

• cd docs
• make html SPHINXOPTS="-W --keep-going"

produces a fair number of warnings->errors per below the fold. I haven't checked the reason for the deviation from the passing CI (and maybe it could start showing up in the latest CI, not sure).
