Partner portal

The partner documentation is now a portal: a landing page, a quickstart, this changelog, a download and version page, and a support page — alongside the existing integration reference.

New

• Quickstart — generate a key, sign a request, and get a 200 from the validation endpoint in about ten minutes, with a troubleshooting table for the generic 401.
• Node.js request signer — the quickstart now shows the canonical-string signer in both Python and Node.js. Both produce byte-identical signatures.
• Download and versions — store links, the URI schemes registered per platform and build flavor, and the deep-link testbed.
• Support — rate limits, timing windows, the key rotation runbook, and escalation paths in one place.
• This changelog — tagged by surface, with Breaking called out.

Changed

• Navigation is now grouped into tabs, with the integration reference split into Start Here, Integration, Backend API, Platform Guides, and Going Live.
• Ctrl/⌘ + K opens search from any page.

No API behaviour changed in this release.
