did you check whether we use jquery somewhere?

@dhruvatr we use a specific black version (see requirements.d/*) to auto-format our stuff.

Review by Claude Opus 4.8:

Overview

Three changes to docs/conf.py: (1) removes the app.setup_extension("sphinxcontrib.jquery") call from setup(), (2) reflows html_sidebars onto multiple lines, (3) reflows the extlinks dict onto multiple lines. Docs-only, no functional code impact.

Verification

• jquery removal — correct and safe. sphinxcontrib.jquery is already in the extensions list (conf.py:247), so Sphinx loads it during config init. The app.setup_extension(...) call in setup() is genuinely redundant. ✅
• black compatibility — confirmed OK. I ran black 26.5.1 with --line-length 120 (the version/config CI uses, per .github/workflows/black.yaml) against the reformatted blocks: both pass. The trailing commas trigger black's magic-trailing-comma behavior, so it keeps them expanded rather than collapsing. No CI failure. ✅ (Note: the single-line originals also pass black, so this reformat is a style preference, not a fix.)

Issues

1. Description ↔ diff mismatch (main concern). The description says "Removed the unused initial extensions = [] assignment." — but the diff does not do this. conf.py:29 still holds extensions = [], and it is in fact dead code: fully overwritten by the second extensions = [...] at conf.py:241, with no append/+= in between. So the one change that would be a real cleanup is claimed but missing. The cleaner fix is to merge the two extensions assignments (delete line 29) — having two top-level extensions = bindings is the actual confusing thing in this file.
2. Stray blank line. The reflow inserts a blank line between the # Custom sidebar templates... comment and the html_sidebars assignment it documents, slightly divorcing the comment from its target. Minor.
3. Churn vs. value. Aside from the jquery line, this is purely cosmetic reformatting that black neither requires nor rejects, which adds diff noise without changing output.

Recommendation

The jquery removal is a legitimate, safe cleanup. Before merging, consider either actually removing line 29 (extensions = []) — ideally collapsing the two extensions assignments into one — so the diff matches the description, and/or dropping the two reformatting hunks if the goal is a minimal cleanup. No correctness, security, or performance concerns.
