// ✅ ปรับให้ตรง backend: ใช้ Bearer token (ไม่ใช้ cookie)
|
|
// - เรียก POST /api/auth/login → รับ { token, refresh_token, user }
|
|
// - เก็บ token/refresh_token ใน localStorage (หรือ sessionStorage ถ้าไม่ติ๊กจำไว้)
|
|
// - ไม่ใช้ credentials: "include" อีกต่อไป
|
|
// - เอา RootLayout/metadata ออก เพราะไฟล์เพจเป็น client component
|
|
// - เพิ่มการอ่าน NEXT_PUBLIC_API_BASE และ error handling ให้ตรงกับ backend
