Confidence Score: 5/5

The PR appears safe to merge because the tracker guard prevents the reported crash while preserving measurement through the existing bootstrap queue when tracking is available.

Summary

This PR prevents a missing OpenAI measurement function from crashing the site.

• Marks window.oaiq as optional in the global TypeScript declaration.
• Skips page-view measurement when the tracker is unavailable.
• Preserves the existing pathname deduplication and measurement behavior when the tracker is callable.
