Chat Layout Responsive Design Test Plan

Overview

This document outlines the comprehensive testing strategy for the chat layout responsive design fixes implemented in Terraphim AI. The layout fixes address critical UI issues where elements don't fit properly on screen when chat history is enabled.

🎯 Test Objectives

Primary Goals

✅ Fix button cutoff: Ensure send button and input controls are always visible
✅ Responsive sidebar: Chat history sidebar adapts to screen size
✅ Mobile optimization: Proper layout stacking on mobile devices
✅ Cross-theme compatibility: Layout works with all 22 Bulmaswatch themes
✅ Performance: Smooth transitions and fast layout changes

Success Criteria

All interactive elements remain accessible across all screen sizes
Layout maintains visual consistency across all themes
Performance benchmarks meet acceptable standards
Accessibility requirements are maintained
No visual regressions in existing functionality
