# Story: Remove Unnecessary Scroll Bars

## User Story
**As a** User
**I want** the UI to have clean, minimal scrolling without visible scroll bars
**So that** the interface looks polished and doesn't have distracting visual clutter.

## Acceptance Criteria
*   [x] Remove or hide the vertical scroll bar on the right side of the chat area
*   [x] Remove or hide any horizontal scroll bars that appear
*   [x] Maintain scrolling functionality (content should still be scrollable, just without visible bars)
*   [x] Consider using overlay scroll bars or auto-hiding scroll bars for better aesthetics
*   [x] Ensure the solution works across different browsers (Chrome, Firefox, Safari)
*   [x] Verify that long messages and tool outputs still scroll properly

## Out of Scope
*   Custom scroll bar designs with fancy styling
*   Touch/gesture scrolling improvements for mobile (desktop focus for now)

## Implementation Notes
*   Use CSS `scrollbar-width: none` for Firefox
*   Use `::-webkit-scrollbar { display: none; }` for Chrome/Safari
*   Ensure `overflow: auto` or `overflow-y: scroll` is still applied to maintain scroll functionality
*   Test with long tool outputs and chat histories to ensure no layout breaking
