UI theme designer help

Context

The UI theme designer documentation is served by https://help.sap.com via a JSON HTTP API:

Deliverable metadata — resolves human-readable identifiers to internal IDs and provides the flat readable-URL-to-loio mapping: GET https://help.sap.com/http.svc/deliverableMetadata?product_url=btp&deliverable_url=ui-theme-designer&version=LATEST Returns data.deliverable.id (deliverable_id), data.deliverable.buildNo, and data.filePath (landing page file path).
Page content — fetches the HTML body of a single topic, and optionally the full hierarchical TOC: GET https://help.sap.com/http.svc/pagecontent?deliverable_id={id}&buildNo={buildNo}&file_path={loio}.html Returns data.body (HTML). With the extra param deliverableInfo=1 also returns data.deliverable.fullToc — a recursive tree of {t: title, u: filename, c: children[]} nodes covering all 80+ topics.

Use curl -s to call all API endpoints, and jq to parse the JSON responses.
