🎨 Design System & Responsive Guidelines

Design Tokens

Spacing Scale (Consistent 4,8,12,16,20,24,32,40,48)

--space-1: 0.25rem;   /* 4px */
--space-2: 0.5rem;    /* 8px */
--space-3: 0.75rem;   /* 12px */
--space-4: 1rem;      /* 16px */

--space-10: 2.5rem;   /* 40px */
--space-12: 3rem;     /* 48px */

Typography Scale (Fluid with clamp)

--text-xs: clamp(0.75rem, 0.9vw, 0.875rem);    /* 12-14px - Label/Meta */
--text-sm: clamp(0.875rem, 1.0vw, 1rem);       /* 14-16px - Body */
--text-base: clamp(1rem, 1.0vw, 1rem);         /* 16px - Body baseline */
--text-xl: clamp(1.125rem, 1.4vw, 1.375rem);   /* 18-22px - H3 */
--text-2xl: clamp(1.375rem, 1.8vw, 1.75rem);   /* 22-28px - H2 */
--text-3xl: clamp(1.75rem, 2.4vw, 2.25rem);    /* 28-36px - H1 */

Border Radius

--radius-sm: 0.375rem;   /* 6px */
--radius-md: 0.625rem;   /* 10px */
--radius-lg: 1rem;       /* 16px */

Container Max-Widths

--container-sm: 40rem;     /* 640px */
--container-md: 48rem;     /* 768px */
--container-lg: 64rem;     /* 1024px */
--container-xl: 80rem;     /* 1280px */
--container-2xl: 90rem;    /* 1440px max content width */

Grid System

Auto-Fill Grids (Prevents Tiny Cards)

.rc-grid-auto {
    grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
    gap: var(--space-6); /* 24px on mobile */
    gap: var(--space-8); /* 32px on desktop */
}

Card Grids with Minmax Rules

• Mobile: Single column, full width
• Tablet/Desktop: repeat(auto-fill, minmax(280px, 1fr))
• Large Desktop: repeat(auto-fill, minmax(320px, 1fr))

Layout Patterns

App Shell Centering

.rc-container {
    max-width: var(--container-xl); /* 1280px */
    margin: 0 auto;
    padding: 0 var(--space-4); /* 16px base */
    padding: 0 var(--space-6); /* 24px on tablet+ */
    padding: 0 var(--space-8); /* 32px on large desktop */
}

Form Grids

• Mobile: Single column layout
• Tablet (768px+): Two-column grid for appropriate fields
• Desktop (1024px+): Three-column grid for complex forms
• Gap: Consistent var(--space-5) (20px)

Data Tables

• Desktop: Generous padding (16px vertical, 24px horizontal)
• Tablet: Reduced padding (12px vertical, 16px horizontal)
• Mobile: Card transformation OR horizontal scroll with sticky first column
• Touch Targets: 44-56px row heights

Accessibility Features

Touch Targets

• Minimum: 44×44px for all interactive elements
• Buttons: Consistent min-height: 44px
• Form Inputs: min-height: 44px with proper padding

Focus States

• Focus-visible: 2px solid accent outline with 2px offset
• Focus Rings: Only visible for keyboard navigation
• High Contrast: Maintains WCAG 2.2 AA compliance

Responsive Images

.responsive-image {
    width: 100%;
    height: auto;
    aspect-ratio: 16/9; /* Intrinsic sizing */
    object-fit: cover;
}

Performance Optimizations

CSS Features

• Fluid Typography: Uses clamp() for optimal scaling
• Container Queries: Future-ready responsive patterns
• CSS Grid: Prefer over flexbox for 2D layouts

Development & Testing

Demo Route (Development Only)

http://localhost:8080/dev/scanner-demo

• Live WASM decoder testing with camera feed
• Real-time performance metrics and statistics
• Fallback server decode testing
• Browser capability detection results

Server-side Fallback (Optional)

# Enable server-side decode (disabled by default)
export ENABLE_SERVER_DECODE=true

# Test fallback endpoint
curl -X POST http://localhost:8080/api/scan/decode \
  -H "Content-Type: application/json" \
  -d '{"imageData": "base64...", "width": 640, "height": 480}'

Build & Deployment

# Build WASM decoder
cd web/scanner/wasm
./build.sh prod

# Copy assets to static directory
cp decoder.wasm ../../../web/static/scanner/wasm/
cp wasm_exec.js ../../../web/static/scanner/wasm/
cp ../ui/*.js ../../../web/static/scanner/ui/

# Docker build includes WASM assets
docker build -t nbt4/rentalcore:latest .

Integration with RentalCore

The Go-first scanner integrates seamlessly with existing RentalCore scan endpoints:

// Scanner automatically calls existing endpoints
POST /scan/{jobId}/assign          // Device assignment
POST /scan/{jobId}/assign-case     // Case assignment
POST /api/v1/jobs/{jobId}/assign-rental  // Rental equipment

// Events emitted for UI updates
scanner.addEventListener('deviceAssigned', (event) => {
  // Update UI, show success feedback
  // Integrates with existing job management
});

Progressive Enhancement Philosophy:

• Path A: Go-WASM decoder worker (optimal performance)
• Path B: Browser BarcodeDetector (if faster for specific formats)
• Path C: Server-side Go decode (ultimate compatibility)
