---
## Key Design Guidelines
### 1. Navigation Strategy
- **Primary**: Top horizontal tabs (Dashboard, Valuations, Approvals, Reports, Admin)
- **Secondary**: Sub-tabs or filter pills below primary tabs
- **Tertiary**: Accordion panels within content
- **Mobile**: Bottom tab bar (5 icons: Home, Queue, Approve, Reports, Profile)
- **Breadcrumb**: For deep navigation paths
### 2. No Horizontal Scroll Strategy
- **Desktop**: Max-width containers (1200-1400px), centered
- **Tables**: Sticky columns, hide less important columns, convert to cards on mobile
- **Forms**: Single column layout, responsive width
- **Content**: Vertical scrolling only
### 3. Progressive Disclosure
- **Accordion panels**: Expand/collapse sections
- **Tabs**: Group related content
- **Modals/Slide-ins**: For secondary actions
- **Conditional fields**: Show only when relevant (bank-specific, property-type specific)
### 4. Responsive Breakpoints
- **Mobile**: < 640px → Single column, bottom tabs, full-width, stacked
- **Tablet**: 640-1024px → 2 columns, adaptive sidebar, 90% width
- **Desktop**: 1024-1280px → 3-4 columns, full layout, max 1200px content
- **Large**: > 1280px → Optimized for large screens, max 1400px content
### 5. Touch-Friendly Design
- **Minimum tap target**: 44x44 px
- **Button height**: 44px on mobile (40px on desktop)
- **Input height**: 44px on mobile (40px on desktop)
- **Spacing**: Generous padding and margins
- **Gestures**: Swipe, pinch-to-zoom, pull-to-refresh
### 6. Accessibility (WCAG 2.1 AA)
- **Color contrast**: 4.5:1 for text, 3:1 for UI components
- **Keyboard navigation**: Full support, visible focus indicators
- **Screen readers**: ARIA labels, semantic HTML
- **Text sizing**: Supports browser zoom up to 200%
### 7. Performance Optimization
- **Lazy loading**: Images, accordions, tabs
- **Virtual scrolling**: Long lists (1000+ items)
- **Debounced search**: 300ms delay
- **Optimistic UI**: Immediate feedback, background sync
- **Caching**: Lookup data, user preferences

## Workflow Summary
### Stage Flow
```
Draft → Survey → Submitted → Review → Approval → Approved
↑ ↓
└──────────── (Backward allowed) ──────┘
```
### Role Responsibilities
| Stage | Primary Role | Actions | Can Edit Fields |
|-------|-------------|---------|----------------|
| **Draft** | Creator | Create, Edit, Submit | All basic info |

| **Approved** | - | Locked | None (read-only for all) |
### Multi-level Approval
- Configurable by bank: 1, 2, or 3 levels
- Sequential approval (Level 1 → Level 2 → Level 3)
- Each level has same approval screen
- Visibility of previous level remarks
