• I passed tests locally for both code (uv run pytest) and documentation changes (uv run jb build docs --builder=custom --custom-builder=doctest)

Note

Low Risk
Doc and doctest markup only; no runtime or API behavior changes.

Overview
Documentation-only updates for Sphinx/Read the Docs.

In triangle.py, the ultimate-values narrative is moved under a proper Notes section (replacing a heading style numpydoc did not recognize). The ultimate-values subsection is labeled with bold text, and the long-format ultimate example doctest now includes import pandas as pd.

On the user guide index, the Triangles card Classes line switches from a broken py:class reference to a Sphinx {ref} to triangle:structure, matching how other cards link to doc sections.

@priyam0k can you review this too? :)

[priyam0k]

thanks @kennethshsu for the nudge to start picking up reviews, still finding my footing here so please correct me if i'm reading things wrong.

@henrydingliu nice, and the rtd preview link works, so the webhook side looks good too.

two things i checked:

the {ref}Triangle `` resolves. the label is defined in docs/user_guide/triangle.ipynb. dropping the bold and switching to … also brings the triangle card in line with the other cards on that page, which already use {ref} and …. minor note for later, not this PR: the other pages use the docname:anchor form (development:development, tails:tailcurve) while triangle's label is just triangle. works either way, just inconsistent.

the Notes block is the last thing in the class docstring, so nothing else gets pulled under it by numpydoc. clean fix.

one nit: the import pandas as pd in that testcode looks redundant. the class docstring already has a.. testsetup::at the top that imports both pandas and chainladder, which is why the earlier blocks work without it. harmless, but if the intent is making snippets copy-pasteable on their own, the other blocks would need the same treatment.

I actually want to blow up the overall panel setup. both this index and the example gallery index. these panels are super finicky. links can become unclickable as you scroll around.

numpydoc seems to reset the environment for every section. doctest actually fails without this new import.

[priyam0k]

the section-level triangle:structure reads better than pointing at the whole page, nice. and fair enough on the panels, if the whole setup's getting redone then the label convention will sort itself out there. good by me.
