Add a dataset (CSV, TSV, JSON, or GeoJSON) to an existing PortalJS portal. Appends an entry to datasets.json so the catalog and showcase render it automatically; routes the data by source (local file vs remote URL) — R2 via Git LFS by default, remote URLs by passthrough. Use when registering a new dataset in a scaffolded portal.

Symptom	Cause	Fix
Fetch fails for a URL source	Non-200 status or unreachable host	Report the HTTP status and ask the user to confirm the URL is publicly accessible.
"Not a portaljs-catalog portal"	`datasets.json` missing	This is an older single-page template; ask the user how to proceed rather than failing silently.
Unsupported format	Extension/content-type isn't csv/tsv/json/geojson	Ask the user to convert the source before continuing.
`git lfs push` has nothing to stream	`git lfs install --local` never ran, so raw bytes were committed instead of a pointer	Run `git lfs install --local` before `git lfs track`, re-add and re-commit the file.
R2 PUT returns 400	A broad `http.extraHeader` was set and replayed onto the presigned URL	Use the `_jwt` Basic-auth piggyback in `lfs.url` only — never a global `http.extraHeader`.
`(namespace, slug)` clash	Another entry already uses that pair	Ask the user for a different slug or namespace.
`next build` fails	Malformed JSON in `datasets.json`	Print the build log, fix the JSON, rebuild before reporting success.
