Local and session storage

  • dv_ui_prefs (localStorage) — Reduced-motion accessibility preference (necessary)

Analytics (optional)

When you accept Analytics cookies we load Google Analytics 4 (measurement ID G-LSV80VFTDP) and Microsoft Clarity (project z1vyg7oxxz) to understand how the site is used. Clarity is additive to GA4; neither tag is injected until you opt in. You can change this anytime under Cookie settings.

Meta Pixel, Hotjar, and similar marketing tags are not loaded today.
