Data Designer Docs Maintenance

Unified skill for adding, updating, moving, and removing pages on the NeMo Data Designer Fern docs site.

Production URL: docs.nvidia.com/nemo/datadesigner (see instances in fern/docs.yml). Source of truth for everything user-facing is fern/.

Scope Rule

ALL doc edits happen under fern/. The legacy docs/ directory is the original MkDocs source — docs/notebook_source/*.py (jupytext) and docs/devnotes/*.md are still canonical for notebooks and dev notes (they feed Fern), but do not add new top-level prose pages under docs/. Concept pages, recipes, plugins, code reference — all of these live under fern/versions/v0.5.8/pages/.

Versioning Model: Floating Latest

DataDesigner uses a floating-latest pointer (matches NeMo Curator). One canonical MDX tree backs both the "Latest" tab and the current frozen train.
