Strictly necessary
Lets the interface honour your cookie decision, rotates anti-forgery sessions when forms post, aligns transport security expectations with hosting limits, persists lightweight UI flags like reduced-motion preferences once you affirm accessibility toggles, and blocks obviously scripted abuse spikes at CDN edges when firewall partners summarise signals.
Analytics
