Authentication Skill

This skill covers Storefront Next's split-cookie authentication architecture with SLAS (Shopper Login and API Access Service).

Overview

Storefront Next uses a split-cookie architecture separating server and client auth concerns:

• Server middleware (auth.server.ts) — Manages SLAS tokens, writes cookies, handles token refresh
• React Context (AuthProvider) — Provides public session data (non-sensitive fields) to components via useAuth()
