+### Frontend Revamp (High Priority)
+
+**Goal**: Improve mobile readability and standardize UI across all templates
+
+#### 1. Database Results Display (Main Content Area)
+- **Current issue**: Tables overflow on mobile, inconsistent styling across templates
+- **Solution**: 
+  - Responsive tables with horizontal scroll on mobile
+  - Card-based layouts for mobile (show data as stacked cards instead of tables)
+  - Standardize column widths and spacing
+  - Improve readability of data cells (better contrast, padding)
+
+#### 2. CSS Framework Standardization
+- **Current issue**: Mixed Bootstrap 5, Tailwind, and plain CSS across templates
+- **Solution**:
+  - Standardize all templates on Tailwind CSS (already in use for `index.html`)
+  - Remove Bootstrap and Font Awesome dependencies
+  - Create reusable component classes for buttons, forms, cards
+
+#### 3. Mobile Navigation
+- **Current issue**: Horizontal navigation bar with 8+ links doesn't collapse on mobile
+- **Solution**:
+  - Implement hamburger menu for mobile devices
+  - Responsive breakpoints for different screen sizes
+
+#### 4. Form Responsiveness
+- **Current issue**: Forms use Bootstrap grid classes, inconsistent spacing
+- **Solution**:
+  - Tailwind responsive grid for form layouts
+  - Consistent input styling and validation feedback
+  - Mobile-friendly touch targets
+
+#### 5. Dark Mode Enhancement
+- **Current issue**: Incomplete dark mode coverage, some elements still have light backgrounds
+- **Solution**:
+  - Comprehensive dark mode CSS variables
+  - Test all pages in dark mode
+  - Ensure proper contrast ratios
+
+### Implementation Approach
+- **Phase 1**: Fix database results tables (mobile scroll, card alternative)
+- **Phase 2**: Standardize CSS framework (remove Bootstrap, use Tailwind only)
+- **Phase 3**: Responsive navigation and forms
+- **Phase 4**: Dark mode polish and accessibility improvements
