sfnext-hybrid-storefronts

Run Storefront Next alongside an existing SFRA or SiteGenesis storefront for a gradual migration. Use for hybrid mode, PUBLIC__app__hybrid__enabled, legacyRoutes (exact, :param, * wildcard, { pattern, suffix }), HYBRID_PROXY_ENABLED, SFCC_ORIGIN, HYBRID_ROUTING_RULES, vite-plugins/hybrid-proxy.ts, the dwsid session bridge, sharing login/cart between SFRA and Storefront Next, eCDN routing rules, cookie domain for hybrid, "[Hybrid Proxy] SFCC returned a redirect to 404", blank proxied pages, or lost sessions when crossing storefronts. Do not use for the cookie-domain settings themselves beyond the hybrid checklist (use storefront-next:sfnext-security), auth code (use storefront-next:sfnext-authentication), or MRT deployment (use storefront-next:sfnext-deployment).
