Refreshed the onboarding template (rendered PDF is gitignored, carries live tokens):
- ✨ NEW §3 "The YouTube → emotion pipeline": /sources fetch → /jobs poll →
/artifacts download → /analyze/emotion, the showcase end-to-end flow (curl + the
@nech/api TS shape), idempotent-on-repeat noted.
- Credentials block now carries BOTH tokens: the api:* Bearer AND the npm read
token for installing @nech/api from npm.nech.pl.
- Endpoint table gains /sources, /jobs/{id} (+DELETE), /artifacts/{cid}/{name}.
- §1 surfaces the live /docs + /openapi.json links and corrects "access": only
/healthz is public now; docs/spec need api:docs (covered by api:*).
- Sections renumbered (pipeline=3, client=4, good-to-know=5, support=6).
