Organize Reference Docs
The full procedure is in references/guide.md — how a grouping is proposed and
checked, the category index page's shape, the sidebars.js rules, and the bounds that keep a
reorganization from breaking links.
This targets an already-written reference section — any set of existing pages you are grouping,
not only the single-type pages docs-organize-types categorizes. Read that skill's own scope note if
the section you're reorganizing is exactly a set of per-type reference pages; either skill applies
there, and this one adds the section-level receipt, the sidebars.js ESM/CJS verification gotcha, and
the ordered verification pass in the guide below.
