Subject: [PATCH] =?UTF-8?q?=F0=9F=8E=A8=20Palette:=20Add=20loading=20state?=
 =?UTF-8?q?=20to=20login=20button?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

💡 **What:** Added a loading spinner and disabled state to the login button.
🎯 **Why:** Prevents multiple form submissions and provides clear visual feedback to the user that their login attempt is in progress.
📸 **Before/After:**
*   **Before:** The button was clickable multiple times and gave no feedback.
*   **After:** The button is disabled and shows a spinner while logging in.
♿ **Accessibility:** The disabled state prevents accidental clicks and provides a better experience for users of assistive technologies.
