📄 Description

Summary by cubic

Updated the cookies docs with a new Cross-Domain Cookies section explaining that cookies cannot be shared across different domains in modern browsers. Added practical alternatives (rewrites/proxy, shared subdomains, SPA token auth, and auth providers) with clear warnings and guidance.
