platform.nginx-routing: replace the stale 'flip map + internal callers in sync' guidance with the new pattern — internal callers point at hiveiq-nginx:<port> and follow the 00-backends.conf map (10-internal-backends.conf). Document the targeted-flip gotcha (global sed corrupts the derived active_color table; bluegreen-deploy.sh has this bug) and 'never recreate the active color'. platform.deployment: add a prod blue/green cutover section + the 2026-07-03 incident lesson.
