For _vis_opt_s to be compliant, it must be:
- Not set on the first visit — not even for a fraction of a second
- A consent banner is shown, and the visitor actively accepts analytics cookies
- Stays blocked if the visitor rejects or ignores the banner
- Listed in your cookie policy with its name, purpose and retention period
- Removed or invalidated when the visitor withdraws consent
