 * Note: hosting platforms such as Vercel and Netlify are intentionally NOT

 * runtime, not just during builds, so treating them as CI would suppress
 * telemetry for every production deployment on those platforms. Build-only
 * signals such as `NOW_BUILDER` (Vercel build step) are kept, since they are
 * never present when the server is actually running.
