A complete list of cookies and similar storage technologies set on this site, including their purpose and retention period.
Performance measurement
We use Vercel Speed Insights to measure how quickly our pages load for real visitors. It collects anonymous, aggregated performance metrics only. It sets no cookies, stores nothing in your browser, and records no information that identifies you, so it runs regardless of your consent choices.
Manage your consent
You can review and update your consent choices at any time. Opening the consent settings reloads the consent banner where you can opt in or out of each category.
