feat: launch voice AI blog with five tutorials and comparisons

[alexanderqchen]

Adds a static blog at orb-ui.com/blog with five articles for developers choosing and implementing voice AI stacks. Product documentation remains on Mintlify at orb-ui.com/docs.

Articles

• OpenAI Realtime API tutorial: complete React/WebRTC example with server-issued credentials and a local-time tool.
• Vapi vs Retell: sourced pricing, browser SDKs, custom models, transfers, and capacity.
• Vapi alternatives: managed services, open-source frameworks, and migration tradeoffs.
• ElevenLabs conversational AI in React: private-agent token endpoint, WebRTC, text events, interruption status, and session cleanup.
• Voice AI platforms compared: architecture selection for phone, browser, and mobile applications.

Provider sources checked September 28, 2026. Comparisons do not claim measured latency or cost winners.

Publishing

Markdown produces complete HTML with canonical URLs, social metadata, BlogPosting/breadcrumb schema, and automatic sitemap entries. Includes responsive reading layouts, table of contents, code highlighting/copying, and scrollable tables. The existing Vite/Vercel pipeline serves the blog. Homepage, docs, and article links connect the five pages without duplicating them in Mintlify. ROADMAP.md and authoring instructions are updated.

Validation and limits

• Full pnpm check passed: formatting, lint, all typechecks, 87 unit tests, builds, and 8 browser tests.
• Tests verify complete HTML, canonical/schema/sitemap consistency, article/doc/anchor links, and exact copyable tutorial source.
• ElevenLabs tutorial source independently typechecks against SDK 1.9.0; six tests execute the published controller with simulated startup, cancellation, disconnect, cleanup failure, and event handling.
• Desktop and 390px browser inspection passed; no page overflow or console errors observed. New external source links checked.
• Mintlify build validation and broken-link check passed.
• No billed OpenAI or ElevenLabs conversation was run for these articles. Provider audio behavior and credentials still need live account validation; each tutorial states that limit.
• Package API is unchanged, so no package changeset is needed.

Review focus: comparison recommendations and sourcing; tutorial agent setup and deployment boundaries; blog routing/metadata; reading and code/table layout on mobile.

Authored with Codex (GPT-6) from the request to launch the blog, add the three approved articles, merge after verification, and include the published URLs in the next-day GSC indexing task.
