 * When the browser talks to the API on a different host than the Next app
 * (LAN Nest, or https://ghabilee.ir from localhost), CORS / SameSite cookies
 * break. Point NEXT_PUBLIC_API_URL at this Next origin (e.g.
 * http://localhost:3008/api/v1) and set API_PROXY_TARGET to the real backend
 * so /api/v1 stays same-origin for the browser.
 *
 * Nest still names/flags the httpOnly refresh cookie from *its* NODE_ENV
 * (`__Host-ghabilee_refresh`+Secure in production, `ghabilee_refresh` on
 * local HTTP). Rewriting local HTTP Next to production Nest can therefore
 * emit a Secure `__Host-` cookie the browser may reject. Prefer local Nest
 * when testing login/refresh. See docs/reference/environment-variables.md.
