Declining this one — the other five action bumps (#153, #154, #155, #156, #159) are merged, but this is a different kind of change wearing the same clothes.

python-version in build.yml, pages.yml and release.yml is not a dependency to keep current. It picks the single interpreter that builds the wheel, bundles web/dist and cuts the release. Three things make "newest" the wrong policy for that pin:

• tests already runs the whole supported range, 3.9 through 3.14, on every push. Version coverage is that workflow's job, not the builder's.
• The wheel is py3-none-any. Which interpreter builds it does not change a byte of what ships, so there is nothing to gain.
• It ties the release pipeline to whatever is newest on the runner. When that pin is wrong the failure shows up while cutting a release, which is the worst time to discover it.

None of this says 3.14 is bad — it is in the matrix and green. It says the choice of build interpreter should be a deliberate edit rather than an automatic one.

renovate.json now disables this update so the PR is not recreated, with the reasoning recorded in the rule's description. That change is on claude/library-demo-plots-webpage-8r8uz4 (#161); until it merges, this may reappear once.
