A shareable getting-started for the hydra-live-hexa Studio: what the Audio
Intelligence API does, base URL + bearer auth, the full endpoint list, a curl
quickstart and the zero-dep TS/Vercel snippet, plus caching/limits/errors and
support. Branded to the Nech.PL APIs / Ship's Bridge look; A4, print-clean.

onboarding.html is the committed template (token placeholder __NECHPL_TOKEN__);
render a per-tenant PDF with chromium --headless --print-to-pdf after sed-filling
the key. The rendered PDF carries a live token, so clients/*.pdf is gitignored —
never commit it; deliver it to the tenant over a private channel.
